As the title says, whenever I try to go into the Dawnstar Sanctuary in the "Cure for Madness" quest, my game freezes. This is the first time I've gone to enter the sanctuary right after talking with Arnbjorn. I enter the correct passphrase, the game goes to the loading screen, I can see the smoke and my current level progress but nothing else. This is where the game freezes. I cannot alt+tab out or use ctrl+alt+del to close Skyrim. In order to get out I have to manually turn my computer off then back on.
I've searched the web and have tried some of their solutions. I've let the game sit for awhile and that didn't work. I have also tried to load from the quicksave as well as saves further back in the quest line. None of these have worked. Any ideas would be great. It would be nice if I could finish this questline.
