I have used ver. 2.50 with a MAP330 successfully for some time. Â I recently got an eXplorist 400 so I found out that ver. 2.8x handled the Magellan USB, so I downloaded ver. 2.90. Â It worked just fine to download waypoints but not tracks. Â I can select the proper track in the Open File window but then it stops and gives an error mesage that says it cannot download the track file. Â Please help.
