I need help with Medieval 2 total war mutiplayer. Time after time as is try to sign on ( with my valid Account at gamespyid ) it tells me agian and agian that my cd-key is not valid and yetit said that it was when i was installing it. I bought the game from ebgames and have a great internet connection so i don't understand. The game was used i think, and i wonder if you could help me? ( Of course i'm going to go and use custormer surport after this just i was woundering if one of you knew what to do.)
