When attempting to load a LR backup catalog, I get the following error message:
Lightroom cannot use the catalog named "xyz" because it is not writable and cannot be opened.
I have been using this catalog for a few years with no issues and I back it up on an external drive every time I exit. I am a novice photoprgher so I don't use it every day. Please help, I still have all of my photos but I do not have any that I have edited in LR. Desperate. Thanks
