i contacted live about it,coz i think it wont let me sign because my region was set to hungary. the other gamertag works but i cant put the code in,coz i already used it with when installed the game. so i wrote i want to change the region. they wrote back, sorry you are ****ed. try to cancel the account and redo it. ill try that,but this is so BS ! many forums about lots of similiar problems,and live just dont give a damn. so why waste 40 bucks for a game? just torrent it..
