Had an update from either Adobe or Microsoft and now my LR catalogue is unreadable, all of the saved ones. Tried building a new catalogue and it only built the original files, no adjustments. Then it refused to make a backup.
Researched a bit and it's quite common, but no fixes.
Really upset.
1am this morning, I imported a catalogue from several months ago and it worked, phew.....
Had to import and adjust about a hundred pics that were missing.
All good now, hope it doesn't affect anyone else.
