Thanks. Can you open up the Catalog Management window (Catalog->Manage Catalogs...) and check it to see if it has any notifications for your catalog(s)?
We're seeing this in your log: existing catalog not found: "/Volumes/IMAGE LIBRARY-MG1/_PHOTOS/pm_catalog 1/catalog.pmdb"
We expect that there is some notification about not being able to open your "pm_catalog 1" database.
