Hi,
After downloading the robo-orb_exercise_start.blend and opening it with blender (2.78c) on my linux (Mint 18.1) machine, I only get an empty scene with the default Cube and the following error message : File format is not supported in file '..../robo-orb_exercise_start.blend'
Same happens under Mac OSX.
Any idea of what's going on? Maybe related to new version of your website?
Thanks for your assistance.
Jean
