I can't start the College of Winterhold quest "Hitting the Books".

I was told to talk to Urag, but he won't give me the quest dialogue, so it won't start. I've tried setstage, recycleactor, talking to Mirabelle, exhausting all dialogue options, etc. They do not give me the quest. Disabling all my mods is NOT an option, because that would break my game and I have many. I've heard I could just skip the quest, but that would break the rest of my quests. Is there a solution for this?
