Multiplayer cd key for halo Tags: PC gaming Multiplayer Games CD-Rom Video Games Last response: June 17, 2010 6:43 PM in Video Games Share Anonymous June 16, 2010 6:57:12 PM when i enter a multiplayer game the system sais: Your CD key is Invalid what should i do? plz help More about : multiplayer key halo fusion_gtx June 17, 2010 12:21:26 AM I'll ask the obvious question, do you have a legitimate copy of this game. And where did you obtain it? If it wasn't from a store it is possible that it's a non-legit copy. isamuelson June 17, 2010 5:39:55 PM Buy the game. If you did, then the CD key should be either on the manual or the CD case. Otherwise, don't ask for help with software that have not been legitimately purchased and asking for keys (even if you bought the game and lost the key) is not allowed on these forums.

If you bought the game used then you are screwed unless you know the original owner and ask him/her to de-active the account. That might work. 2. If you bought it new, then go back to the store and ask for an exchange. 3. If you illegally downloaded the game, then just buy the game you deadbeat. Can't find your answer ? Ask !
