Could you try to download upbge from here https://download.upbge.org/ then run that version of blender and open up my jimbo.blend file from my package with it? Then select "Start Game engine" from the top Game menu drop down? It's possible that your gfx card doesn't support the newer version of GLSL that UPBGE uses but it would be really helpful if you were to test it out for me. Thanks again for the feedback and clearing up your error.
