When I sign in on my Xbox360, my profile screws up. It will sign me in but soon after, either if i wait or a start a game, it will kind of half sign me out again. I mean, I will be able to see all of my friends, messages and my party but my profile picture
gets greyed out, and if im in a party, the party screen freezes and its like i am, effectively, not signed in... If i sign out and back in again it will be fine until I power the Xbox off.
