Topomap not working on Basecamp???

Hi there, I have a Garmin GPS 64st with a top map of Norway. The map is named TOPO experience PRO ver 3, and I'm running Basecamp on my MacBook Pro. It has always been working fine, but now I can not see much details on the map, just an over view. I have Mojave ver 10.14.4 on my Mac and ver 4.8.3 of Basecamp. Is anyone know something about this problem?? Does it have something with 64 bits or what??
