iMovie starts OK and appears to be working on other projects, but I've got one project that appears to hang iM whenever I try to preview ("play") it. I'm at a loss and need help! I'll croak if all my work is damaged.
The problem started not long after I stopped a "Share" to the media browser. That stopped OK and I added a song afterwards, which now appears in the right place after quitting and restarting (ie. the edit appears to have completed OK). But now I cannot preview any part of the project without getting the endless beachball. Activity monitor shows high CPU usage while the ball spins, but nothing else happens.
I've tried restarting the computer with no luck. I've got over 25 Gb free on the HD. Please tell me there's a way out!
