Using the downpatcher I went from 1.6.9 to 1.6.3, then 1.6.3 to 1.1.30, everything works fine and runs fine up until I leave the vault and it loads into the commonwealth and your character shields their eyes, just after when you regain control the game crashes to desktop, no message or anything. I've tried running it in every compatibility mode and nothing has worked and I can't find anything on this. Any help?
