Hello, my apologies if this has been answered recently. I have searched, but all of the relevant posts are several years old, and the software has changed a lot since then.
I recently upgraded my 2014 MBP to a 2020 MBP, running Catalina, and Basecamp 4.8.8. On my old laptop I had installed the files from my TOPO US 24k DVD into Basecamp using the installer on the DVD. However, when I migrated my files from the old laptop to the new, the installed maps no longer appear in Basecamp, even though they exist on the hard drive. I still have the DVD's and I would like to install them into Basecamp on the new laptop. I have tried the installer that is on the DVD, and MapManager, but both fail. Is there anything I can do to re-install the maps into Basecamp?
Many thanks in advance for your help and advice!
