Well i'm having some difficulty in the CoW questline, Hitting the books wont start no matter what i try. i have done this quest before many times and had no issues. im thinking this is because a while ago for some stupid reason i disabled Ancano, I knew at that point i will encounter some bugs when doing the questline. i spawned another version of him but that obviously didnt work. is there a way to spawn the original version of Ancano? im almost 80% sure that will fix it and let me carry on with the quest.

To respawn a character, you must use the following sequence of commands, here for Ancano:

prid 0001E7D8

enable

moveto player

Do that in the College.
