happens after login to the 'games for windows live'
my graphics card drivers are up to date.
my soundcard drivers are up to date.

i dont see anywhere to 'update' games for windows live.. and i thought it was supposed to do it on it's own.
i went and downloaded the gfwlivesetup.exe from the xbox website .. that should of given me all the updates necessary for this game to function.

i dont see a sticky thread showing the list of common fixes.
i havent gotten my money's worth from this video game.
