Need some help. I have downloaded and unzipped with no problem. It created a single .img file. I want this to be in Mapsource, so I used the tutorial find here at noeman.org. It compiles correctly and I run install.bat. It is listed in Mapsource, but it is a blank white map. I can zoom all the way down and see a white page, or I can zoom out to the max and see a small white box, but never any map data.
Where did I go wrong?
