Try trashing the iApps preference file. For instructions, see this post.

You need to upgrade iMovie to '11. AFAIK, there no other way to make it work. iPhoto '11 uses a new database which cannot be read by older iMovie versions.

I've solved the problem by empting the iPhoto trash. Simple solution.
