So when I try to play call of duty modern warfare 3, I get this error message that says "the current profile is not allowed to play on xbox live." grrrr how do i fix this. I dont have gold membership thing, but ive been playing for a long time with out it. i tried everything to try to fix it and now i changed by gamertag and all my stuff was lost on call of duty. do i just need to buy the gold membership because its not letting me go on xbox live at all!!!!
