I-Movie 11 hung up

[easy9595]

I-movie 2011: I was trying to import movie off my desktop to I-movie and it locked up. It says "optimizing movie" and nothing happens. I did let it run overnight, I-movie quit responding. I did restart several times, still same. Can't get to other events that I worked on in my event library. It does force quit the whole I-movie and not the "optimizing video". Please help! THanks
