iMovie isn't loading.
I am working on a school project. I haven't used iMovie in a long time, I only opened it the first time I got my Mac book Air. When I click the Icon, a grey box pops up in the middle of the screen. Nothing is popping up. The top bar is apparent. When I click the buttons, like start new project nothing happens. Help fast, for my presentation is tommorow. If not it is okay.
