Does anyone know why the Dawnguard guy (Isran?) is instantly hostile toward me when I enter the Dawnguard castle to join? My character is not a vampire or werewolf and has zero assaults/murders and I have never accidentally hurt/killed a member of the Vigilence of Stendarr. Also, loading previous saves doesn't help either. It's REALLLLLYYYY frustrating because I made this character specifically to become a volikar vampire and now I can't even start the Dawnguard questline. Any help or suggestions are much appreciated.
