Looking for Twinhan 1020a Drivers for Vista 64

Sorry if this has been answered, but I really tried searching first.

I'm running Windows Server 2008 64 bit, but so far it's worked with everything meant for Vista 64 bit. I'm trying to run the Twinhan 1020a DVB-S card.

I've got the codecs and BDA drivers loaded as I read on a Hauppauge forum. I installed the 64 bit version of ProgDVB.

The problem is that Vista device manager can't find the correct hardware drivers for the card. Hopefully the files exist somewhere. Does anyone have the instructions to get the drivers loaded?

Thanks for any help.
