I have the same problem and still can't find out what to do. I have gone to each and every single province and stolen a small thing and gotten rid of my bounty that way so it's not that problem I have heard that wearing daedric armor sometimes makes them attack you but I'm wearing roughspun robes and I do not have a follower. I am a Vampire and have completed the Vampire lord questline but i changed back into a werewolf and they still attack me. I need help!!!!
