So . . . what I discovered on that LaCie hard drive was that it was frozen n "In progress" and I could not access any of my past backups on that hard drive. So, I dragged the fles into the trash, where they all opened. I was then able to g through the backups and retrieve what files I wanted and then empty the trash. I'm sure I lost a lot, but I now have an empty back up drive and I located a lot of materials I thought were lost forever. Still no Piano vocal score Finale files for the newly edited "Babes In Toyland." Oh, well . . .
