Thread: cgpsmapper Error E3032 Layer 0 of the map cannot be empty

I have .jpg image from a topo map. I opened the .jpg in ExpertGPS and geo-rectified the file. I opened the geo-rectified file in GPSMapEdit and saved as .mp file. Then I put cgpsmapper.exe and the .mp file in the same folder on my (Windows) computer and opened a command prompt and typed: cgpsmapper.exe mytopo.mp
I get this error message: Error E3032 Layer 0 of the map cannot be empty.

Any ideas how to fix this? I am trying to convert the .jpg to a Garmin .img file format. I am not aware of any "layers" in the .jpg file, it is just a picture from a topo map which I added the Long-Lat coordinates with ExpertGPS. In GPSMapEdit, in Map Properties, I have two layers listed.
