How To Fix The Crysis 2 CD KEY IN USE Error

A lot of our customers have been emailing saying that when they try to join a crysis 2 multiplayer online game, they get ‘cd key in use’ error.

Don’t worry, this is not our key problem. It is a known crysis 2 game bug. Best of all, it is very simple to fix!

Many people are having the problem that the game doesnt remember the serial key and shows ‘key in use’ when multiplayer. This will be patched – it is a problem with CRYSIS 2 not our keys. but for now: heres a fix!

1. Open crysis 2 and log in
2. Click on multiplayer, and put in your serial key
3. Return to singleplayer
4. Go… back to multiplayer and enter your key again.
Now the game will work

Another solution known to work is:

If you get key code in use error when jioning multiplayer, this is a known game bug. Try joining an EMPTY server, then your key will ‘register’ and you can join any match.

We hope this helps!

You can read an interesting review written by CJS Customer kosmo2409 below

Now before all of you rage at me i want to make 2 things clear.

I am not a CoD hater. I played and own all the Cod titles from literally Day 1 of the original CoD release on the PC.

I just feel that they could have done better with the programming of this game, IE hit box fixes, dedicated servers, and better spawn system.

I have no issues with perks or weapons. and I feel that CoD still has a strong overall system. And the campaign is always pretty sweet.

Now with that being said the second thing i want to point out is this is not a fanboy rave about Crysis 2, I just want to compare. And i know that there is a crysis 2 sub forum but this thread is primarily about Cod and how crysis is like it so I direct this at the CoD multiplayer forum base.

Now to start off, I downloaded the crysis 2 MP demo on xbox yesterday.

After getting my butt handed to me in several matches I finally got a feel for the game, how it works and i unlocked all the nifty little extras that needed higher levels to unlock.

After A while i realized I was playing CoD, on steroids.

Here is why.

1) Killstreaks. Black ops you can buy killstreaks and when you get the kills , you can use them. In Crysis2 the killstreaks seem to be the standard 3-5-7 set-up with radar for 3, orbital strike and radar jam for 5, and a ceraph attach ship for 7. the level 5 seemed to switch between matches.

I’m not sure if there are more or not but I did notice that the even when i called in a ceraph ship aka kinda like attack helicopter, i would only get about 1 or 2 kills tops with it. So other than radar and radar jammer kill streaks really arn’t meant for racking up kills, just to add some support.

2) Black ops has perks, set up into 3 tiers, with 5 options in each tier. Crysis has 3 nanosuit modules, Armor power and stealth, just like the 3 tiers in cod. and within those modules there are 6 options each. they even have advanced upgrades for the module choices just like pro versions in black ops. So far out of the 3 in each group you can use nothing seems really over powered, even stealth (which i was super worried about) is not very powerful. there are a lot of anti stealth things and even when someone is stealthed its not perfect, you can see blurs in various lighting situations, and if they run through water you can see the run off.

3) Guns, so far black ops wins with guns, i’m not sure if they will offer more guns in crysis 2 when it comes out but in the demo there are 6 classes of guns, sub machine guns, assault rifles, shot guns, heavy machine guns sniper rifles and heavy guns. so far there were 2 SMG choices, niether you can use in the demo, 5 AR, only one used in demo, 2 Snipers 1 used in demo, 2 shottys, 1 used in demo, 3 lmgs, 1 used in demo, and 2 heavy weapons, none used in demo. there are also 5 side arms guns, only 1 used in demo.

the guns feel and shoot well, hit boxes seem to register very well too. they all seem to have 3 classes of attachments that you can have on at the same time, scopes, barrel and under barrel attachments. one of which is a hologram, pretty sweet to use.

4) map. Maps so far are comparable to black ops. they are more detailed and more interactable in crysis and in release i believe there will be 12 maps. demo only has 2. in the crysis maps you can swim underwater too which is pretty cool. but so far maps are same with black ops just with way better graphics and design. imo.

5) Overall playstyle. It’s fast, i mean i thought black ops was fast paced but this is unreal. the fact that you have the energy bar, which drains when you sprint, slide, or jump up to grab and pull yourself up a high ledge. this adds a crucial part to the game. the bar reloads pretty fast, like 2.25 seconds from empty to full. certain actions combined make it drain fast too. if you sprint across the map, slide then jump up to a high ledge you will be pretty much out of energy preventing you from using armor modules power or stealth.
there is also a visor that drains energy but it allows you to see through stealth. everything is intertwined and the gameplay becomes more , how should i say this, strategic?

you have to manage a lot of your actions, this games energy bar system, mixed with the high adrenalin action can really open up a lot of sick kills.

for instance i was sprinting with armor on, a guy was stealthed sprinting towards me, he fired a shot which droped him from stealth, the shot hurt me but since it wasnt a head shot i was barely alive with armor. i slid he jumped to perform an air stomp. i ended up killing him but was then quickly killed by a sniper shot. i saw the kill cam of the exchange and it really did look sick.

i understand in the other maps you will be able to kick cars at players as well.

6) killcams, they both have them.

all in all it seems crysis 2 took a lot of concepts from Cod. the game truly does feel like Cod on steroids. In my personal recomendation, this game does take some skill. you have to have good reaction time as well as quick thinking ability. decisions are typically made in your face and instantly. I will be picking this game up most likely. along with homefront to satisfy my fps needs until battlefield comes out.

If you played the demo, let me know what you think and how it compares to black ops, what you like better about black ops and what you like better about crysis.

based on my above summary, ik know i know TLR right?

1) Killstreaks, CoD has more options but i like that they are not game makers or breakers for crysis, just support.
2) Perks, i actually like the armor modules in crysis better, they seem more balanced and they even gain their own xp based on how much you use them.
3) guns, guns are ok in crysis but black ops def has more of a selection.
4) Map, crysis by far wins graphically and in design.
5) overall playstyle black ops was fast but could accomodate casual players, crysis is faster on steroids but may frustrate casual players due to higher learning curve.
