mod or cc throwing exceptions but I need help pls.

I was wondering if someone can help me figure out what mod or cc could be causing my game to stay stuck on the loading screen after loading the main menu. I would be so appreciative to any help that is offered to help find the solution to my problem. I've been so dedicated to my latest saved game that I would be so sad if I have to start a new save. (I have also restarted my game without my latest save and it sometimes loads and sometimes wont).
