my cd key -1 reply

i put my cd key in after i logged in on multiplayer and it said it was ok... so i joined a server and it said to put it in again . so i put it in again and it says that its already in use :confused: . any one have any ideas of what i can do?

mine did this for a while after i bought it then all of a sudden it starts working... so dont give up on it.. if the game is illegal well duh.. i thought my game had an illegal cd key but it just wanted to be gay for a while saying that it was invalid.

The same thing happens to me but it never stops and I know its not an illegal copy.
