I used the back up command to put all my pics in PSE11 on a pc. I want to transfer them to a mac. I used a thumb drive, but when I try to restore the pics to the mac, I get"disc in drive "my catalog" does not contain a valid BU. I have examined the thumb drive and all the pics are there. What to do?
You used the organizer's back up command and you've installed PSE on your mac, right? Look in the backup file for the .tly file and be sure the restore location is on your mac and not the backup drive itself. Do you know how the thumb drive was formatted?
