I can not get into the College of Winterhold in Skyrim. I know I am supposed to talk to Faralda, but she is nowhere to be found. I accidentally attacked a guard in Winterhold and now she is gone. I can not continue with the Dawnguard quests without getting in there.
If you have an outstanding bounty, you can skip Faralda straight and go into College of Winterhole... (it's one of the bugs)
There's nothing to say you have ho go into the college to continue with Dawnguard; you can find out the location of the moth priest by asking inn keepers or carriage drivers.
Or, if it's the Elder scroll you're after, you can by-pass the college and go straight to Septimus Signus' outpost.
