My lightroom and photoshop was moving very slowly. I closed everything, backed up lightroom catalog, shut down my computer and did a restart. When I launched lightroom, I got an error message stating "catalog 5 is corrupt and can't be opened until repaired. I selected repair. It said it could take several minutes, but it . It came back with another immediate error and asked if I wanted to try again. I tried many more times. Same thing. So, I went to the creative cloud and it showed that there were updates for lightroom, photoshoop, and bridge. I did all of the updates and tried to relaunch lightroom. Which, I was then able to successfully open lightroom, but the folders were old. There was none of my new work. All current edits...gone...eeekkkk
You need to restore a recent backup of your catalog file.
This actually didn't work. That was why I wrote the message. The back-up catalog was saying it was corrupt so it was not reloading it.
I was hoping someone might have a suggestion to fix a corrupted back-up file.
However, when I reloaded the file into lightroom, the edits that I had done, brought into lightroom, and back in were saved in that file, so that saved me on a lot of the photo's.
