Hey everyone I finaly got into skyrim again and then this bug happend. I got serana out of the crypt, walked up to volkihar and... nothing. She didn't speak to me befor approching to warn me to let her talk, and she didn't talk to the gatekeeper or open the gate.

I've tried fast traveling to and from volkihar and other places, reseting the system, even electocute the gatekeeper. Nothing works.

Help Please!

Try that:

Use a platter to go trough the gate into the castle. The quest should continue as normal.
