Crashing when clicking on a project

I worked on a project and everything worked fine. The next day, I open up Final Cut, click on the project to select it in the browser (not even double clicking yet to open it), and FCP immediately crashes.

I have 2 projects with this problem, and I can no longer open them. Has anyone dealt with this problem? Any ideas on how to salvage them? I'm worried that work has all gone down the drain.

 

Ok, after days of tinkering I found some random things that finally helped me save both in different ways.

1. delete the CurrentVersion.fcpevent file in the project folder in the package contents of the library file
2. open FCPX - you'll get an exclamation mark because it can't find it
3. close FCPX and reopen it
4. one project was selectable and openable; the other was selectable but would still crash after opening

EDIT:
Screw it, I thought I figured a way to open the 2nd project, but it's still crashing. Well at least I saved one of them so far.

Also another weird thing is I closed and reopened FCPX, and the first project suddenly had a different name and it crashed when I tried to open it. After closing and reopening again, it had the original name and I could open it again.

I had difficulty finding anyone online who had the same problem, but if you do, hope this helps.

But after these issues, I am really nervous working in FCP X now. Luckily I had already finished both of these projects and sent them off. But I've been asked to provide a 2nd, slightly alternate version which led me to reopening them. I shudder to think if this happens when I'm still working in the middle of a project(s).
