Let me begin by saying, this is getting tiresome now. This is the Brink forum damnit! Mod's stop moving posts to try and drum up popularity for this game.
Back to the point: I've not got that far in Skyrim, but I suspect that you are playing a PC version? I assume restart does nothing? While I can't say for sure as I have the console version, it may be that it's a save related issue I can get bugs like this which only affect the save/character I'm playing.
Do you have a earlier save that you can back up to to see if that's the case?
