Everytime i attempt to enter Egrim's Elixirs, go to the kill the ice wraith area of the Stormcloaks quest, go to the area around Hillgrund's Tomb the game locks up. It does not CTD is simply stops responding and forces me to alt+ctrl+del to get out. No log is generated, i have reinstalled the game, ran all updates, and even today i purchased Dawnguard in the hopes that it would update these areas so i could travel there. I can only guess that there is some corruption in the files associated with these areas.

Any help is appreciated, at this point i can not play the game. Is there any way to get a refund if this is not fixable?
