Make sure the USB cable is run from the projector to the computer. You might also want to open device manager (right click my computer>properties>hardware>device manager) and make sure the projector does not have a yellow triangle with an ! on it. You can also try unhooking the USB cord, deleting the projector from device manager, then hooking the USB cord in again to reinstall the drivers. It should all be stock drivers, so you shouldn't need to download anything extra. Also be sure that the batteries in the remote are good and working. Sometimes you can point an infrared remote at a digital camera and see the light on it (I've never gotten it to work though) to verify that it's working.

You can find that information here:
