Parent of resource is marked as read-only error

I can not export a Library Package from Catalyst. When I select the "Export Library Package.." option from the file menu, I am met with the following popup:

My Catalyst project is named "Design"

This happens with every Catalyst project I have tried so far. I am running Mac OS 10.5.7 on an Intel C2D Macbook. I have not run into any other import / export errors so far.

Thanks--
