Help!!! I upgraded to Version 12 last night... my images got an arror when trying to export. I closed LR and tried to do Backup- backup failed... put my Mac to sleep- woke up this morning trying to open LR and nothing!! Errors!!! 😩 I need my images!! 😭
Fix the first error message: go to the folder where the catalog file is stored. In that folder is a file whose name ends with .LOCK (might be lower case). Delete the .LOCK file. DO NOT DELETE ANYTHING ELSE.
