In the first Soul Reaver game, there is a part where you have to ride an air current to fly upwards. There should be a cutscene after that, but at that point my game crashes. I think it's before the fight with Zephon. I did that part once and didn't have any issues then I left without saving and now I can't go up there anymore because it crashes every time. Can anyone give me some tips on how to fix this?
