I just redeemed a 1,600 Microsoft Points Card and I went to change my GamerTag, I successfully changed it, everything's good.
So then I went to start up my game, and when it was on the loading screen (the game, FIFA 11 in this case), it disconnected me from Xbox Live, and when I tried to sign back in, I got the error message "Your Xbox Live Membership isn't valid", so I tried recovering my GamerTag because I thought this was a last resort kind of thing, and it didn't let me finish, it gives me the error message "Xbox LIVE signup is currently unavailable. Please try again later".
Now, I've shut off my console several times, and when I go to sign in to my account, an error message pops up then instantly disappears, and the 'Signing In' screen comes up, and it stays and has been like that for the past 10 minutes.
Does anyone know what's wrong???
