I used cgpsmapper and followed the instructions on this website, but now when I open Basecamp it says that map was not installed properly, re-install and try again. I assume the family ID is not compatible. This occurs even after uninstallilng and re-installing Basecamp. I tried to uninstall that mapset using mapsettoolkit, and it says it cannot be uninstalled. So I'm completely stuck! How do I uninstall that mapset so I can use basecamp again?
