ok so after many hours exploring im now stuck on the main quest on the way to fight alduin again ive come across a door which has 3 moveable rings ... I HAVE THE RIGHT COMBINATION and i know this by looking at the diamond claw via the inventory screen. what do i do i have already been out of the whole complex and back in which allowed me to move the rings(they didnt move first time i went in). i cand fast travel out of the area or call the dragon back to leave and the door wont let me through. anybody any ideas for getting round this or a fix?
