I bought Fallout NV for ps3 not long ago, and i just now tried to play it. It downloads all the system updates, but then a black screen shows up that says sSysUtil_AutoSaveWarning: No Default string. Must be loaded from INIFile then just has ok for me to select. if i select the ok, the game doesn't play and just stays at a blank black screen. Is this a disk problem (i bought the game used but there are no visible scratches on it) or a hardware problem?
