WMDC not working on Win7

[jbass350z]

OK. I have a strange problem. I built a new PC and loaded Win7 x64 on it. Everything was working fine. I was even using my TP2 to tether. This worked for about an hour. After a few reboots and software installs, I could no longer connect to my TP2 either through tethering or through WMDC.

I struggled for hours to figure out the problem, but nothing worked. Finally I reinstalled Win7 hoping that would fix it. Nope. It did not. No matter what I try, Win7 fails to install the driver for the device. I have downloaded new copies of WMDC from MS and that hasnt helped.

Any thoughts? It is working fine on my Vista machine.
