Pmosh

Please help. I'm playing the Crimson Plague quest in Tribunal. I killed all the rats and the evil dead woman and made my way back to the Temple Basement. When I try to go through the door of the basement, the game crashes every time. I tried loading from an earlier save point just after I killed the dead woman and same thing. I'm stuck. I don't have any mods or tweaks... just the game of the year edition as downloaded on Steam (Oct 2012).
