Hi,
so I'm trying to get this thing here to work on my PC
http://teamfortress.tv/thread/5067/?page=1

I followed the steps as described in the guide.
I'm in test mode and signed the driver (moufiltr.sys), which seems to work (it says the NGO signature is ok).
When trying to install the .inf file I get a error message saying something about the signature not beeing right and the mouse cursor locks in place.
This is the error message I get:

Does anyone have any ideas how to fix this?

I'm using Win7 64bit and a Zowie FK (tried other mice though) if that's important.
