So I have fixed my map, had to re-instal Skyrim...

BUT NOW ... I was making some of those sunburst arrows by talking to Serana and I accidently turned myself into a vampire. I already had Aela turn me back into a werewolf once before so now she won't do it again! How do I turn back into a werewolf now?

If i recall you can only become a werewolf twice so the only way you can fix it is to reload

By reloading an earlier savegame.

JC!
