Sunix USB2302 Windows 8.1 driver problem

I am running Windows 8.1 x64 and am having a problem with getting my Sunix USB2302 working. I have downloaded the drivers (Renesas chipset) but the card is still coming up as not working in device manager. My gut tells me its a driver issue, but I have the latest installed.
Can anyone help?
