OK. I hear about the different versions that I have but only one reply about whether it was safe to uninstall the other versions. Well, I uninstalled the old Lightroom and, using the Creative Cloud application, uninstalled Lightroom CC. When I opened Lightroom Classic CC it asked me to update the version of my Catalog, which I did. Now, despite saving catalogues regularly, I have a catalogue that is months old and not reflecting the days of file reorganising I have been doing. I also don't understand why it gave me a new Catalog reference "-3". Is there an easy way to get my latest Catalog back?
