Yesterday purchased and installed a new resource: Collins Bible Companion. Prior to yesterday, Logos would occasionally "hang" requiring a restart. Now Logos stops working every time I try to use it.
Please delete the following file: C:\Users\Les\AppData\Local\Logos5\Data\043rugpg.fje\LibraryCatalog\catalog.db
When you restart Logos, it will run "Preparing your library" for a few minutes to rebuild it; after that, it should run normally.
