I have a valid Mapbox key entered into the ST16 and into the desktop version of DataPilot. Both will list all the available Mapbox maps (of which there are many) but none will resolve onto the screen. I'm able to view those same maps on the Mapbox web site. I've tried several without success using DataPilot while the same maps from Google, Bing, etc. show up just fine. Any ideas on what is going on?
