yeh assassins creed was installed before just like black ops
i tried installing black ops again but same problem. i deleted my cache but it still doesn't work.
i also deleted the game of the hard drive and attempted to play the game on the disc but no luck.
i fink i shud go bak to playing bad company 2
just updated and guess what!
for some reason i can no longer play call of duty black ops. it appears on the dashboard with the "play game" written on it and i have it installed on my hard drive and have been playing the day it came out. when i play it the console freezes with a black screen and the eject button and guide button dont work.
p.s. assassins creed brotherhood still works
just checkd out your theory
its offical - the update added ap2.5 checks on black ops, modern warfare 2 and halo reach
it kinda figures seeing as the update took a while to complete. it did seem as though there were big changes taking place.
now we wait.....
