Hi, I recently changed my name on xbox live from the 360 dashboard. I can log into live through halo 2, but when i choose matchmaking it says "Updating Configuration Files, please try later" so i come back later and it says "failed to update configuration files required for matchmaking. Sighn out and sighn back into live to fix this problem." so i do what it says and the exact same thing happens. Whats wrong? Plz can sum1 help me.
