Problem loading apache driver on Vista

[latemasterd]

Problem: Error in loading "Microsoft Windows Mobile Remote Adapter" states that "The required device registry key does not exist."

Device: xv6700 with WM6.1 from PPCkitchen.org
Computer: Vista Business with WMDC 6.1

Things that I have tried:
-uninstalled driver in Device manager, plugged back in, same error
-uninstalled and reinstalled windows mobile device center 6.1; same error
-tried reverting to windows mobile device center 6.0; same error
-uninstalled wmdc, ended all mobile program in task manager, stopped the two mobile device services, plugged in phone and still failed.
-unchecked "enable advanced network connections" on phone under Settings/System/USB-to-PC, plugged back in, and it loaded "Microsoft USB Sync" as the driver. This did not interface with WMDC or allow me to sync at all, despite the driver loading successfully.
-turned off firewall, still error
-hard reset device; same error
-tried on other vista pc, and it worked just fine. problem therefore lies in the pc.

Any ideas as to what could be causing this? This computer was just fine before, now all of a sudden the driver wont load. I REALLY dont feel like reformatting my PC (especially since it still might not eliminate the problem). From researching online, it appears to be an issue for other phones as well.
