Mapsourse - cgpsmapper white map error

Hello, I'm having white maps when I install diferent maps for mapsourse with cgpsmapper...
It's really difficult to make a good selection, this white map goes right when I zoom the map at 200km.
What's wrong here? Hope is the cgpsmapper but i'm not sure...





Thanks!

That might be something to do with the zoom levels set on the map itself, which means different things on the map will disappear from view at a certain zoom level.
Perhaps you could try changing the zoom levels?
I've only used GPSMapEdit for edting in the past & to change the zoom levels using that it was File > Map Properties > Levels.
I guess the software you're using would have some way of changing the zoom levels.
