uninstall all the drivers and thrustmapper. now intall the thrustmapper and drivers from teh CD.
reboot etc etc.
then goto thrustmaster site www.thrustmaster.com and click support. then find ure wheel and download the unified drivers.
this is how i installed them...
plugged my wheel in, right click my computer, properties, hardware, device manager, right click my wheel (not the HID one but USB one) and properties, drivers and uninstall. now the hid and usb drivers are gone.
unplug the wheel.
run the driver installer and plug it in when it sais to, then hit next quick
thrustmapper will say updating inf file etc. in xp u will get driver not certified.
click continue on that.
