Product Code has been registered with another LIVE ID??
I bought the game when it went on sale a while back, and played through the campaign no problem. I just tried to log into GFWL to play multiplayer but it says my Product Code has been registered with another LIVE ID. I do not have any other LIVE ID's.
I contacted Windows LIVE support and they said that cont help me as its a product key issue on Time Gates end. I tried contacting them in their FaceBook, official fourms and contact us email but NOTHING back from them. Im so irritated at this, any help or advice?
