So, I restored an older version of the project using Time Machine.
Did as you suggested and created a copy of the current project file.
Copied one of the missing audio files into the Media folder of the new copy.
Worked like a charm!
outstanding! nice when a sudden thought actually works, glad your project was rescued.
Thank God for backups.
you can't say that loud enough or too many times! i wish everyone would remember: without backups you _will_ lose work. maybe not today or tomorrow, but you will at some point, and possibly _everything_
