Everything was okay last night, bought some stuff from Farengar, and saved. Today, loaded the save up, and the entire place is extremely bright, I can't move, and I can only move my head up and down. I can open Tab and access the Skills and Magic menu. The skills menu has the titles of the Perks trees and the progress bar, but the perk trees themselfs, with the text describing the perk, isn't there. Opening the Items menu causes a CTD.
Help me. Loading earlier saves results in the same effect.
