About a week ago my profile appears to have disappeared, although when I log in it allows me to log in but my avatar, gamer score and rep are not showing. Also when I start up a game I have to go through the setup process each time I log in, even if I've just played the game, went back to the dashboard and then back into the game. I've checked all of my settings and they are as they've always been for the past 5+ years. The only thing that I can think of is that I've added in the Media Center settings, so I disconnected that and still nothing. Reconnected and still nothing. I've recreated my avatar and it won't even show my new avatar.
Any ideas of what might be going on?
