So I headed my may towards the path towards the Daylight Cavern. (I think that's what it's called. The cave that leads the Dawngaurd Keep.)
NOTE: I ran into a horse like 50 kilometers East from the cave with the option to steal. I did kill a random killer on the road but no innocent victim near the horse.
Inside the cave, I approach the man walking up the road and starts to attack me for no reason. I ran from him, not attacking, and everyone in the vicinity gangs up on me. Even the person whom I suppose to talk to attacks me.
So I'm thinking this isn't supposed to happen so I can't start up the quest right.
NOTE: I'm not a vampire, but I did try my hardest to be. I'm not a werewolf either. I am clean.
NOTE: I re-downloaded the dlc on a different xbox and load up the same save files. Same problem.
I'm thinking of starting up a new game and see what happens. I'm also going to delete the DLC 1st before I begin a new.
If this was already covered. My apologies I've search for a good while and nothing popped up.
