I had that same problem!
I have an idea of what you might have done wrong.
On the map maker program you saved your map after you were done right?
Well there are actually two different ways to save it. One of them is at the bottom of the screen. but then there is also another option at the top of the screen, it says scsave, if you use the scsave, the map should work in your program.
