iMovie crashed and my latest project has disappeared

Hi,

I've been working on my latest project for many hours when all of a sudden iMovie crashed. When it reopened it asked me to repair my library, which I've done many times before when this has happened and all my projects usually remain.

This time, my latest project disappeared completely. I've tried looking in the backups folder as suggested on other posts but the latest backup was from a few days ago and now it's restored a number of projects I'd already deleted and none of my recent projects are showing.

All of the media and files for the new project are showing in the package contents of the iMovie library but I can't seem to access or find the project. It's taken me ages to get to where I was and can't face having to do it all over again :(

Any ideas?
