Ive just started playing this so I dont know exactly all the names but I will try to describe my problem.

The problem is this:
I have killed the dragon and now I am going to give the greybeards the horn.. but as soon as I step inside the door, everybody rushes towards me and casting freezing spells against me, and then fire and then ice until Iam dead,, I cant see why this is happening? before when they learned me shout and stuff there was no problem, and Ive googled this and didnt find any answer, other people also got attacked but not when they were going to give them the horn.. Can someone please help me and tell me whats the problem, if it matter Iam an dark elf (and a vampyre? I think..)

Perhaps they dont like vampires

It's the vampire part.

Check your crime stats on the menu and see if you have a bouty for the region you are in. I was once notorious for killing a chicken in Riverwood.

You...you....MONSTER!!

well.. okey what can I do about that? I dont even know how I became a vampyre.. how can get back to normal?

Okey I′ll do that too, even if it isnt the vampyre stuff thats messing I still dont wanna be a vampyre
