I am using Photo Mechanic Plus Version 6.0, build 4617 (3eb3787) iMac MacOS version 10.15.4 5K 3.6 8 core i9 w72GB ram. I have this happen 3 times now. I open PM Plus and I am missing a entire catalog. I have the default and Photo current catalogs available. I had a catalog of NFL photos as a test. I did in 2019. Did not move the drive or location of those photos. In the catalog management tab it shows the catalog in Red "Failed to Open Catalog" Still has the folder in location of the drive with catalog.pmdb and proxies folder. Not sure if i am missing something here
