IMovie HD 6.0 LOCKS UP On Launch

Question

I have spotlighted everything 'iMovie' and deleted the files. I have reinstalled this several times and cannot get past the startup screen.
When I click to start a new project and specify the location, a status appears, loads halfway, and never goes away. Sometimes it leads to other complication with my G5.
What is causing this?

Answer 1

1) Is there in fact a project named "My Great Movie" that iMovie is trying to open?
Upon first launch, I tried to create a new movie. The default file name was "My Great Movie". It asked to specify a location. Afterward, the smaller 'status bar' window appeared as if it were launching the program.
The status bar remains at the halfway mark, trying to load thumbnails or icons. The program will not load unless I work around it by going to the file menu.
2) Does the problem occur when you launch iMovie by clicking the iMovie icon in the Dock? Or how exactly do you launch iMovie?
Both. I've completely removed it and reinstalled everything related to iMovie. I have a new icon in the dock and also have tried using the one in the applications folder.
3) Does the problem occur when you launch iMovie by double-clicking some OTHER project?
Yes. I can bypass the 'locked' status bar window and select 'New' in the file menu. I specify a new name and location while the status bar zooms to complete. The program will then appear and I can work like normal. The status bar remains on screen saying that it's loading thumbnails or icons (at 100% complete).
Be sure to discard the iMovie preference file with iMovie NOT running. Otherwise iMovie will write the bad data back to the preference file as it quits.
I used spotlight to uncover everything iMovie related. I deleted .plist, .pkg, and everything else I could find. When I reinstalled, it does the same thing.
Odd, I know. I've got 6.0.1 and I'm running 10.4.6. I'm not sure what else to do!
