"please exit game".
This is the message I get when I try to run GoW3 off the internal drive, Hermes 4b, 160gb slim. Tried Open Manager and Multimanager (newest versions). Have a bluray game disc in the drive.
This is the only game I have a problem with. When I first started using backups, I got the same error message with Demons' Souls, but it turned out it was because I was trying the direct launch, rather than going back to XMB and clicking the disc icon. With GoW it doesn't work either way.
GoW is on the compatibility list as working fine. Any ideas? I tried it without updating the game, and with updating it.
