I have owned the game since launch and all of a sudden it says my multiplayer code is invalid. Anyone else have this issue? Anyone else wish EA wasnt a gaming company?

YES!!! I have played this game (multiplayer) succesfully yesterday evening, Today I try to launch(multiplayer) and it says serial code incorrect..

More info:

Steam version patch1.2 , the key code is exactly the same nothing changed on my side from yesterday evening and now, I believe crytek released a very small update to fix the loading times in STEAM crysis 2 and by that there is a bug that says that our code's are invalid for multiplayer

Any info about this crytek staff.. I can't acces mp now.

Hey guys, the simple solution to this problem is to re-enter your valid key code. If you are 100% sure it is correct and no-one else has used it, and you continue to have problems, then you should get in contact with EA support who should be able to assist you further.

Quite a lot of people are having this problem even after re-installing and re-entering they key, and it obviously is something messed up on Crytek on EA's when valid cd keys are beeing denied, especially after hours and hours of using those keys. Anyone who dealt with EA support before knows exactly how useless they are and I doubt there's anything they can do in this situation, so unless they're gonna start giving people new keys, that's not a solution, that's stalling.

I was able to do multiplayer until the update, now it says "invalid serial code", I re-enered it and still no go. I bought the Limited edition from Gamestop, and have not shared my code with anyone, should I contact EA support? This has never happened with any game before, I have been gaming for over 20 years , so it's really frustrating.

edit- I tried to enter it again and on the 3rd time it finally worked!
