I dont bother using the CH manager software, only causes me greif when I unlpug on of my CH units to plug in a steerwheel or joy pad.
I unload all the CH stuff (Some click buttons in the managers) then let XP redetect it all and use it that way.
Set the default game device to the Stick, even though in my case the Pro Peddles apear at the top of the list.
Then allocate the axis to each controler in AH.
