I got a new Xbox, and downloaded my profile to it, no problem. Played a few games on it, then decided it was finally time to change my gamertag. Changed it, then decided to download xfinity. After xfinity downloaded, my Xbox restarted. When I went to download my profile again, as it requested, I got the message "Profiles can not be downloaded at this time", with the error code 80151006. I've tried clearing the cache, deleting the profile and any corrupt files from the Xbox before restarting it, then trying to download the profile again. Still no luck. It always gets to about 40kb before the message pops up. I did notice that my old gamertag is still being used on this site, but my new one is shown when it is trying to download the profile. Seems there might be a communication error somewhere. This is extremely frustrating seeing that I just spent $450 on a new Xbox, just to not be able to save anything on it.
