I traded for a xbox360 e. I downloaded my profile and started downloading my games to it. I went to turn off controller after several days updating queue but I turned off console. My profile would disconnect from xbox live after I powered back up. Assuming it was corrupt profile, I deleted it and went to download it again. BUT, I get sorry, there's a problem with the credentials.. blah, blah, error code 8015190A. I tried Everytjing, please help!!!
