    Lightroom couldn't update the format of its catalog because file appears to be damaged

      I had to rebuild my Windows 10 machine and installed the new Lightroom Classic.  Previous version was older, although can't exactly recall which LR version.

       

      I've tried opening my old catalog (300gb) and get the following message:

      Lightroom couldn't update the format of its catalog because file appears to be damaged

      I'm certain it isn't as I was using the catalog fine before rebuilding the machine.

       

      Searching the forums this seems a common problem when upgrading from older LR versions, but I can't see a fix?

       

      Anyone any ideas?

       

      Thanks
