My iMovie crashed due to running out of disk space - now files missing
I movie ran out of space due to my HD becoming full from render files. Now when I open I movie I can't see any music library songs at all. I think it's opening the wrong library or a corrupt library or something. I've searched for the old backup libraries but can't open them. Please help, I want to start a new project and use music.
