Guys. I have problem. When i try to open Crysis 2 on steam (i bought it there) I get the activation Thing up. I succesfully activated the game a couple of days earlier, but now it asks me to enter my serial, i enter my serial but then i get error 1005 : The serial code has been used to manny times blablabla. I have only installed this game once!?!?
Anny reply would be great

Thanks

Pirates stole your CD key.

Gotta talk to steam

No guys, my CD Key is not in use, It has been used to manny times, and i have only used it 2 times to activate my game
