Sorry to be negative, but I doubt if 3198 fixed it. I uninstalled 3191, copied my previous folders for 3062 back in place and reinstalled 3062: all disk settings and data were then back to normal. Then I went directly to 3204, since that has the new settings backup and restore feature, bypassing 3198. The result was that no settings were retained (except for 1 of 11 disks, oddly) and all disks needed to be scanned for the first time.
(This time, however, I did a printscreen of my names & locations, and re-entered everything into 3204. I'll let Scanner rescan everything and just move on to the future.)
