I've been using FCP X for a while, creating clips and sharing to iTunes for display on my Apple devices (Apple TV, iPad, etc.) After the 10.0.6 update the other day, I loaded FCP and it said I needed to upgrade. So I did. I cooked for a while and apparently crashed (came back later and FCP wasn't running). I re-launched it and ALL MY EVENTS WERE GONE. I could see projects and I see the event folders on the Video volume, but FCP didn't see them. I destroyed my preferences and it went back into upgrading my projects (apparently). After noticing files being updated in my event folders, I decided to let it cook. The next morning, FCP appears to be normal.
After digging through discovering how to export to iTunes again (29 second clip), I tried it but it hangs. Background tasks shows Sharing -> Processing: Transcoding clip <clipname>.
I also let it cook for an hour, but it never finished. Anyone out there have any ideas, cuz I'm a little pi$$ed.
