Hi all, I have a problem with iMovie that I can't solve. When I open the program up it almost immediately comes up with a window that asks "The previous attempt to open this movie failed, do you want to ignore it? Yes or No?" Regardless of whether or not I choose to ignore it iMovie stops responding and comes up with the beach ball and I have to force close the program. I tried to locate the .avi files which it mentions, but I think I deleted it from iPhoto some time ago. I'm running a 3 month old MacBook Air, OS 10.8.3. Any suggestions please?
