iTunes has stopped working when adding movies
This issue began today, haven't had any trouble with this before. I have my movies on my iTunes, in there perfectly fine. Today I went to add more movies to my iTunes library. I use Windows, so I went to the 'Add Files to Library...' option in the top left, added a video. It didn't take any loading time, which seemed a bit out of the ordinary, then I tried to play it and my iTunes completely crashed. When I open my iTunes back up, the movie is gone completely. I have tried restarting my iTunes, restarting my computer, reinstalling iTunes, adding movies in different ways (dragging and dropping), but nothing has worked so far.
I'm fairly sure this isn't a format issue, as it's stopped working for .m4v files and .mp4 files, I've tried converting one to the other and nothing has for it to load properly into iTunes.
