Well, I'm on the quest for retreiving the Jagged Crown for the stormcloaks. Me and the other stormcloaks got to the part of the dungeon where you are supposed to match the three emblem rings on the door to the ebony key I picked up from the floor, but when I try to activate the rings so they can turn, nothing happens. I tried backtracking to see if there is a lever or button i had to pull but nothing. Am I supposed the do some part of the main story or another quest before I can open that door? In the main story, I still have to retreive the horn of jurgen windcaller.
