I have exactly the same problem. I an running on a desktop Vista, VantagePoint was intalled all right. I also have "Mapsend Topo USA" and "Mapsend routes and destination Canada". I cannot see any maps on the right part of the screen. They do not appear on the list of the left part of the screen either, just the base map. I am now trying to use an Explorist400 , but still have a beat-up Sport Track Pro. I still hope for a solution.
