Upon trying to get in to the dark brotherhood sanctuary my game freezes as the game loads it up. I'm talking about the sanctuary that burns down. I've already completed the dark brotherhood quests. I also have a companion with me. Why am I trying to get in there you may be asking? I've misplaced a dragon priest mask and I can't find it anywhere! I sure wish there was some kind of search system in place for things that you own or "possess". That would save me a whole lot of frustration.

So when you try to enter the Sanctuary it freezes? Have you tried clearing your system cache?

When the game freezes I open my disc tray to get back to the dash and load the game up again and i get a black screen. I dont think its my system because my console doesnt freeze, just the game. At the black screen I can still hear sounds but I can't move or bring up any menus. I know I can't move cause I don't hear any footsteps or attacks.

*update* I can see! I waited the black screen out for about ten minutes and everything is working fine now. I got a message saying my follower couldn't come inside with me. Probably why I was having this problem.
Thanks anyway.
