Imovie not responding

Hi,

I have looked up ways to solve the problem of imovie not responding, and after deleting the preference files, opening itunes and iphoto, and repairing the disk, then restarting I have managed to reopen it a few times. However every time I close imovies I have to go through the entire process again when trying to reopen. Now I have done all of those steps and imovie still refuses to open. All I get is the spinning wheel of death and I have to force quit. It's the most frustrating process ever. I am up to date with imovies on version 10.0.5. Someone please help!
