I'm encountering a problem at the beginning of the game and cant progress. After blowing up the reactor Cloud and Barrett go back to the Avalanche hideout. When taking the elevator down to the basement during my game the elevator immediately goes back up and the game cannot progress. Ive tried fresh copies of the ISO to no effect. I don't have access to my original disc and don't have a CDROM installed in my computer anyway. Any idea if this is related to my video settings or corrupted ISO?
