I don't see any solution to this, I've tried everything that's been recommended :( My gamer profile is showing as corrupted, it won't connect to Xbox LIVE although the other profiles on my account (which are LIVE profiles) are fine, and can connect. My profile connected by default on sign in, but showed my gamerpoints as 0 and my avatar as blank, but now it's not even doing that. I tried to recover my gamertag, but I get the "Xbox LIVE signup currently unavailable - Try again later" message. I've also heard about people losing their saves, even though they chose not to delete them when recovering their gamertag, which scares me a bit. I don't have a memory card or anything like that to transfer my profile to either. I've got no idea why it's corrupted, I've done nothing wrong!
I don't know if it might be something to do with the fact that when I try and return to dashboard after being in a game, the drive makes some funny noises and the screen just remains black - it's like it's trying to quit the game but can't. Mind you, that hasn't happened in a while because I try to avoid doing it, it's only happened a few times, not for a couple of months at least, and my profile has been fine until now. Any suggestions? :( All help appreciated, thank you!!
