Error -49 opWrErr File already open with write permission
Trash the preference files while application is NOT Running.
This use to help
An easy way to find out if this is the problem is by
• Start a new User-account
• Log into this
• Start iMovie - Does it work OK now ?
If OK - then the problem is most certainly in iMovie pref. file in the old User/Library
