Crash at Korriban Caves (Kreia/Atton Scene)

[Reyiss]

While going through the Caves on Korriban, I have had no problems with crashing until I get to the scene with Kreia She speaks to me and tells me we will help you. I said we who only the 2 of us are here, then atton walks in saying she is a dark jedi, I tell them to calm down we have to work together and then the game crashes. I have tried all possible combinations of answers at this point and I dont want to loose my save to get passed this point. I dont have any mods installed and have patched with the 1.0b patch. Anything I need to do to get passed this, any help is appreciated.
