Yes, I know that the Key light is the only shadow casting light by default, and that it comes in at the 12:00 o'clock noon position and you have to rotate it to get an angle. I did read the manual. I still have never been able to get a shadow on the ground object. As a test, turned on the built-in ground plane and stood my character on that. Shadows rendered fine, but with the ground-plane off (as the instructions say) there are no shadows on the World Kit Ground. If you have an example of this being successfully done, I'd like to see it. BTW - I do see shadows in the "preview" but not in the final render.
