Grandtec Pci Card Gxg-9000 Driver Problem

Hi, I have a Grandtec Gxg-9000 Dvr Pci Card thats has been laying around in our shop for a couple of years at least for which we can't find the drivers. We are currently trying to use it in one of our desktop to do some video surveillance. (We temporarly need 5-6 more cams in the office for a demo) The problem is grandtec seems to be out of buisness, i've looked all over and emailed their support team and couldnt get any answer. We're looking for any drivers that would support the grandtec gxg-9000 card. The os doesnt really matter, windows 7 would be great but any option will be much appreciated
