Looks like you're still stuck in the dark ages of Newtonian laws of gravity and 20th Century physics!
I don't currently have DBPro installed, I refreshed my PC recently. I also didn't include a compiled executable in the tutorial to test the original
I checked my archive and I have test code for Torque, Meqon (which became PhysX), Nuclear Glory and Newton - but no ODE executables.
I found the attached code, I have no idea what it does but see if it is of any use.
