I went to this forum, did the tutorials, downloaded a gazillion times and I had the same problem as ez. Finally figured it out... There is a DROP-DOWN box in upper left corner of MapSource...it said PC Map. When I clicked on it I found the maps I was downloading. With internet, sometimes it's hard to know what you're looking at... For the experts--sometimes the uninformed don't know the simple things...we don't know what we don't know...sometimes it's as simple as saying "after everything, be sure to click on the drop-down menu in the upper left hand corner that says PC-map or No Map to see your map". Just my two cents. Thanks.
