Trespasser DLC: Game Freezes When Trying to Enter Deep Roads

Hello,

I am currently playing the Trespasser DLC for the first time, but every time I try to enter the eluvian leading to the Deep Roads, the game freezes. It goes through the loading screen with the tarot cards, then it freezes when it gets to the black loading screen. The green eye in the corner stops pulsing, and the music starts looping, too.

Here is a link to my DxDiag: http://hastebin.com/timaraqaxe.tex

Thank you so much for any assistance you can provide!
