OpenMW doesn't work

Every time I launch the game through OpenMW, the entire screen becomes white or black for 3 seconds, then closes again. But when I go into the data files through OpenMW and disable Bloodmoon and Tribunal, the game will launch in a dungeon somewhere, I can't attack or really interact with anything. Noclip is always on and can't be disabled. I own the steam version of the game if that helps... I hope you guys can help me with my problem :)
