Panda PhysX

I’m on Windows. When I type that command in, I get the same as before.
The output of the console is this:

DirectStart: Starting the game. 
Warning: DirectNotify: category 'Interval' already exists 
Known pipe types: 
  glxGraphicsPipe 
(all display modules loaded.)
:util(warning): Adjusting global clock's real time by 1.8599e-005 seconds.

And the Panda window is still unresponsive.
