Just looking at your screenshot and for those few that downloaded the Windows plugin some spherical maps. (zipped, attached)
The spherical map should be open in gimp as an image or a layer in your image. All you have there is a text layer and a background of some sort.
You do of course need the spherical map option ticked, still on normal map in your screenshot.
...but I am sure you know this already
