I am having the same problem. Worked hard for hours to get a project done and suddenly disappeared!
I had 7 projects in my Project Library and now I only see 6. I see the file in the finder but it won´t show up on Imovie. I have read all the tips and erased the famous com.apple...plist file and nothing happened.
According to what I have seen, we may be at a dead end. It seems that Imovie is unreliable. Sad because I thought that this kind of stuff didn´t happen on a mac (by the way, a brand new MBAir).
Any other solutions would be highly appreciated. Just sharing my frustration!
PD. Sorry for my english, it is not my native language.
Hi Rour and vc38,
A number of others here have posted about this problem, including me. See the following threads:
It's best to report this to Apple, as the more they hear from us the more likely we'll get a fix (hopefully). There is probably a common issue with this, but I'm struggling to think of what may have triggered the problem. Was it a "recent" update to iMovie or OS X Mountain Lion, or perhaps another updated app conflicting with iMovie?
To report the problem to Apple, in iMovie's menu click on iMovie > Provide iMovie Feedback.
PS. Your English is fine Rour
