To enable motion in No limits 2 you need to tell the game that is should output the telemetry used by SimTools. In order to do that do the following.
Open your steam client and login to the account that owns the full game. The Demo will not work with the simulator as the plugin is made for the full game.
Remember to patch the game before you run it.
Once you have installed the game on your computer a shortcut will appear on your desktop.
