Reply to Guitar Hero Control Mapping: Need Help

Ok, I am having a few issues with making use of the How To DJ Using Guitar Hero tutorial posted months ago. I have Xpadder. I have a PS2 to USB converter. I have a GH controller with batteries. As I understand, this and a bit of creativity is all you need to pull this off.

BUT...

When I try to hit the buttons in my Windows 7 control pannel to check the Game Control setup, nothing registers. I have batteries. My device manager recognizes the USB adapter for the wireless GH controller is connected (my laptop beeps and the LED on the GH control connection lights up).

What am I doing wrong? How can I correct this? Without WIN 7 registering the buttons on the control are being pressed, I can't move to using XPadder to create the keyboard commands for TSP or create a .tsi file.

Any suggestions?
