Ok basically, all i want to do is download new rosters. so the game is brand new and everything. When i go to xbox live, it searches for user information and then i don't have any so then it creates one. but when it says creating profile it freezes. i restarted the console like 10 times and still happens. i put in nba 2k6 and it works fine. i tried searching the forums but couldn't find any info on this.
