I Just recently after downloading Dawngaurd and all of a sudden The College of Winterhold dosen't work anymore. I get up to the post were you are suppose to talk to the Mirabelle Ervine. Normally when you first walk up to her she's in argument with Ancano , but IAncano is not showing up. She's just talking to no one. Then I talk to her go on the tour but she tells me to go to my first lesson and I can't because the main hall doors just crack open a little and nothing happens, I even tried console commands and those don't work. I remember this happening to me before a long time ago. I've tried now with 3 new games and 3 saved games they all wont let me into the main hall.
