Can't get my CPU to recognize my PS3 controller.

[darklord63]

I use Vista 32-bit and I'm trying to get my Dual Shock 3 controller to work on my CPU using this program: Sixaxis Dualshock 3 Connecting via USB on windows | MotioninJoy
I installed the drivers sucessfully, but when I go to Control Panel>>Game Controllers There is no controller when I have it plugged in. When I press the main PS button it does not connect, and I do have my PS3 unplugged. I know the program works, but my computer is not recognizing the controller. Anyone have any advice or a surefire program that will work?
