Nothing orbits in Universe Sandbox...

[valbayeros]

I recently install Universe sandbox and nothing orbits around nothing in the game. Every body follows a straight path from its initial position and direction of movement. I can't change Orbital parent or Orbital elements because are in gray.

You've installed a cracked version. This problem occurs because people don't crack it correctly, you will need to actually purchase the game here: http://universesandbox.com/buy/
