upgraded to iMovie 5, now it won't launch. repairing permissions, forcing prebinding update, restarting, changing my socks - all no luck. Have all the latest system updates. Deleting the imovie preferences doesn't do anything (doesn't even recreate new ones after they're deleted and the app is attempted to launch). I get 1-3 dock bounces, then nothing.

Any thoughts? dual 2, 10.3.8

Have you tried opening it from Applications?
Drag alias out of dock and create new one ..

Yup, no luck. I ended up deleting the package contents (show contents, delete contents folder) then reinstalling from the CD (not the DVD). Seems to launch fine now, but i've not had time to play with it to see if it's fully functional..very odd.
