Hi Agnes, have you tried saving your custom maps into your user directory under C:\Users\(yourID)\AppData\Local\SAS\JMP\Maps\ or C:\Users\(yourID)\AppData\Local\SAS\JMP\Maps\11\Maps\ (on Windows)? The location for custom map files has changed for JMP 12 as we now use the Roaming folder for Windows AppData profiles. I recently added a custom map shape file that I have been using in JMP 12 and JMP picked it up when I placed it in my C:\Users\(myID)\AppData\Roaming\SAS\JMP\Maps. I believe JMP 11 still used the Local rather than the Roaming folder. Hope that helps!
