I just want to come back Serana's home, but I am unable to enter the castle, the door don't want open. i take the boat, i go to the castle, after the guy open the first door when he see Serana and Serana tell me that her home,, blablabla, when she ask me if i'm ready to enter in the castel, i try to open the door but it's not working. I even disabled all my mods and even Unnoficial Patch, but nothing works. Can you help me please? thank you.
