I just installed a X-Box 360 wireless controller for Windows and the USB receiver. I installed the Windows 7 64 bit driver off the web. The light are on the receiver and controller. When I launch MW3 on my PC, the controller does nothing.

I can't find any info on how to assign game controls to the controller. On the M$ site I only found the safe way to discard it...this doesn't suprise me with MS these days.

Any suggestions why the controller isn't working and how can I assign game play to the controller?

Thanks,
Mike
