iMovie 10 have to force quit during update of Project files
I have installed Mavericks and now have the newest iMovie. I get the following dialog box (see below) when it is on the last file during an Update. I click "OK" and then the bar continues to scroll and I get the spinning beach ball. Finally I have to force quit iMovie as it is not responding. I have tried just having it import just the most recent movies but get the same dialog box. When I try the old iMovie 9.9 it loads all the projects with no problem. I had two projects that used movies created on an iPhone 5 so I removed those two projects from the projects folder, but no change.
Anyone have a suggestion on how to correct this situation?
I guess I can just work with new projects in this new version as the projects I've been trying to update are completed and saved to other media.
iMac, OS X Mavericks (10.9)
