I had a representative that was not helpful in solving my issue remotely logged in to my computer last night and he left my lightroom in a test catalog. How do I get back to my catalogs. Help please!!!
Go to File > Open recent, and choose your original catalog.
Once you have established your correct working catalog (and made a backup of it), the operating system can be used to delete the test catalog "Test.LRCAT" file and its neighboring Previews folder.
