MC crashed when scraping

I'm new to the program but I feel like I'm going to like it.

MC already found several movies in my movie folder but it crashed at a certain movie and I don't know why or which one. After restarting it just says "scraping move 1 of X'" Nothing happens and eventually it crashes. Any help appreciated

Is there a way to delete movies from the DB base?
I noticed the function "tools" next to profiles help etc. but clicking on it doesn't do a thing.

Thanks again for the program.
