Changed my GamerTag, using the website. This was fine, until the Profile BIO screen came up and I hit save. This resulted in some "Oops you found and error", or something like that. Turned on the 360, my old GamerTag was there, I tried the Recover, after a bit it came back with "Could not sign on at this time, try later". Power down box, rebooted ran XboxLive test (passed) my new GamerTag was up so I I try to sign on and now it just sits there endlessly signing on. Help!
