when i open imovie, it freezes. why, and what should i do?
I have a very important project to do for school and have to give it back next week. It's on iMovie, and it's a 54minutes video. Since yesterday, I have a problem. I don't know if because it's too big, but when I open it, it freezes, and the little rainbow turns and turns and turns..... And because of that projects, I can't start any other project, and I can't go on any other project. That really freaks me out. PLEASE HELP ME!
