D'oh. Thats what I get for speed reading. My bad.
Yeah, it's starting to sound like one movie is corupted or missing.
The files are such: D_ropego.avi (3,142 kb), Gold1.avi (19,296 kb) (only playes on,ce on your first visit), U_ropein.avi (3,051kb). I suspect a problem with the later one. Make sure you have these exact files, and try playing them in media player.
For the record, are you cheating at all? Like is Sephiroth in your party or something? Adding characters whoa ren't supposed to be in your party yet or at all sometimes screws the game up at random points and makes crashes mroe likely.
