So, I just came across this problem this week. Although it's typically my mode to NOT install updates arbitrarily, I did allow BaseCamp to update never knowing I'd have an issue with 3rd party maps.
So, worked my way around the Net, and finally came across this thread. Big shoutout to Boyd for your detailed instructions. It was a huge help.
I uninstalled BaseCamp, Mapsource and MapInstall. Then tried to install BaseCamp 4.6.2. Still had the issue, so I uninstalled and went with version 4.5.2. Worked like a charm and now my maps can be previewed on my Garmin handhelds.
Thanks to all the others who've posted with their suggestions too!
