Going to need more info.
OS you are using.
Exact version of LR.
What is the exact error message you get.
Thanks for the response JSM.
Error message is something to the effect of can't open the catalog, do you want to open another. I attempt to open it again and check the integrity it says there's an error but may be able to be fixed in the future. I have a backup from about 12 days ago that works but I'm missing many hours of work...
Thanks for any suggestions!
Do a search on your drive for .lrcat.lock and delete that file then try to open LR.
A Lock file is created every time LR opens and is supposed to be deleted when LR closes. If LR crashes it can't delete the lock file and LR then can't open the catalog file.
The lock file will be in the same directory, Folder, as the LR catalog file.
you know, I saw that file and just thought, that’s new, just more LR clutter. Interestingly it has yet to crash to my knowledge but my GF uses the MacBook sometimes too.
I’ll try this later today and post back.
Guess I was wrong, .ircat.lock is not present when LR is closed so that can't be the issue. Here are some screenshots of the various messages I see. As mentioned, opens fine from a backed up catalog of about 12 days ago. I tried changing the name of the catalog but that didn't work either. I should mention I've been running this from a USB 3 SSD but when I put the bad catalog on the internal SSD, it still won't open.
