I can't launch LR anymore. According to LR, my catalogue is damaged. LR tries to repair it but the following error message appears: "Assertion failed". Anyone who can help me?
Restore a recent backup copy of your catalog file.
It did not work. LR keeps saying that it can't repair the catalogue.
Try making a new copy of the backup catalog, place it in a brand new empty folder, and then double-clicking on it there.
