Sorry, I'm just searching for a driver. I tried to search everywhere for a driver for this card on Windows Vista x64 but I couldn't find any, even on the manufacturer's website. So that I'm asking if someone have a solution or anything...
It could be that they haven't even developed a driver yet for Vista 64. There are many companies that have yet to do this. Have you tried contacting support and asking them when and if they have a Vista 64 driver?
