Blender 2.66 Smoke doesn't render

Hey I have this simple tracked scene set up but for some reason I can’t render the smoke. Can someone please look into my blend?

Thanks, Blendermonkey

i have the same problem…

actually i think its happing because i took my nvida Gtx 550 for my ATI internal graphics card…maybe blender dosn’t support your graphics card

After that, select Smoke Adaptive Domain, like the image :
