AU Demos Causing 'File Not Found' When Save Logic Projects

I recently installed the evaluation versions of all the Stillwell and Schwa AU plug-ins.

Immediately after doing so this problem started occurring.

Whenever I save a Logic project, Logic now gives me an error pop-up “File Not Found”. I OK it and can then save the project without further issues.

This only occurs if the “Include Assets” option is selected on the save dialog.

I tried removing all the plug-ins, removing Logic prefs, restarting the computer. Didn’t fix it.

Logic 8.02 PPC/OSX 10.4.11
