Freezing problem... *spoilers dark brotherhood*

#1 Posted by ChileanPenguin (25 posts) -
Have a brand spankin new disk and have been playing for several hours. Get to the Dark Brotherhood mission where the Night Mother offers to save you as the santuary is burning down. I step in, she tells me to go to sleep, screen goes black, and never comes back. Is this a common problem? Ive had this game freeze before, but never at the same point. Ive tried walking into the coffin like 10 times and it freezes every time.
