I have an External HD connected via USB 3.0. The first total backup worked fine. When I tried making an incremental backup (directions are confusing). I made a new folder, found the first backup file. Backup calculated the space required. Started backup, then crashed with "Organizer has stopped working" The organizer is then also closed. Tried to make a fresh total backup... crash again. I can use a third party file backup and syn without a problem. However, I need a backup of the catalog otherwise all the tags, etc (purpose of the organizer) are gone. Need a solution or I'll just use the organizer as a basic file viewer like in CS3. PC is running Vista Home Prem with 4 gig ram. Drivers are updated, as far as I know, to the last available updates.
