VirtualCDHide style programs help

[Phsion]

Hey all, i've been trying to NFSMW off an HD Image of the CD, but it seems as if none of the virtual drive hiding programs work on my gaming computer. I've tried sf4hide, antiblah, antiblaxx, virtualCDHide, plus several others. None of them seem to actually work, even though, with the exception or virtualCDhide, they all say they are working (VirtualCDHide says all drives are UNHIDDEN no matter what option i select). On both my other work machines it works fine, just not on my gaming machine. Anyone have any idea's why? My gaming machine is running XP SP2, with admin rights, and im using alcohol or daemon tools, trying everything i can think of, including starting up in safe mode. Thanks for any help i get.
