I bought Crysis 2 in the Steam.
I installed the game started, and brought the key to gain access to a multiplayer game.
And I decided not to go the first available official server.
But I could not go, I encounter the error: "This key is already in use '
Hepld me,pls

I'm getting this problem too. I have the steam version and the cd key linked to my steam account keeps saying its in use. This game has turned into a waste of money so far.

Have the same problem, instant action (fast game) works fine.

What I did:

• download via steam
• install and unlock the game files
• start the game and entered the game key on login screen
• try to play a multiplayer match via server browser
• error occurs: "key is already in use"

WTF? What did I do wrong?

After all games always statistics 0!!

Anything it is impossible to refine!

fix?
