kelly: You're not going to believe this...
Because OSX couldn't find the Retrospect catalogue file, I restarted back in OS9.2 and using Retrospect Express 5, restored the files that had been corrupted. They were fine. So back to OSX to drag them to the OSX desktop. On opening them, found them corrupted again.
So, restart again in OS9.2, and do another restore, but this time the darned files came up corrupted.
Am at my wits end. Mind you, that's not very far!
