I save my map in Polish format with 8 digits.
Go to export said file, again naming it 8 digits.
When I hit run on the CGSMapper.exe pop-up...it doesn't do anything. Blank screen.
It was working just fine on previous maps (didn't have them set as right coordinate system).
When you save it in GPSmapedit give it a written name rather than numeric. I use the same name in both places, in the setup of map properties and for the .mp filename. Before starting map set tool kit rename the map .img file to the same 8 digit name you used in gpsmapedit/map properties. Then use that 8 digit number as the filename in mapsetoolkit
