I have same problem. I haven't played skyrim while but I have been installing new mods and I tried skyrim online and I also downloaded that new update. So I am thinking maybe this is cause of that online mod or new update... Maybe I'll try reinstall this game... EDIT: Reinstalling won't help :confused: FIX: I am not sure if this work for everyone but it worked for me. First I removed/uninstalled skyrim then just try your old save (save before you did something wrong). This might help those who have installed skyrim online or new update.
