I just started working on an editing project for a friend. She's letting me use her computer (Mac OS X version 10.4.11) and FCP software (5.0.2). I had it open a couple hours ago, but then closed it so that I could plug the camera in and have the software recognize it. Now when I click on FCP to open it, it brings me to the "Register Your Software" window (if that far) and then shuts itself down. I've tried rebooting a number of times, but no luck. Suggestions?
