I've been getting this every time I try to leave the interior of Raedric's Keep, regardless of level or exit choice. It started occurring when I tried to exit to the bailey through the dungeon and now every time I try to leave, all I get is a black screen, with either a no access cursor or occasionally a movement cursoer. There is no load screen at all for me. Will deleting the files help resolve this?
