Query: No windows 64 support

I purchased this for the same reason the other reviewer did - middle of the road price. Big mistake!Despite their advertising drivers for Windows 64 bit, they don't support Vista-64 at all. They also don't support Windows XP Professional 64 bit with Intel! When tech support is contacted, the basic response is tough luck - you have choosen the wrong processor, we only support AMD!Avoid this product if you need future-proofing. And it calls into question Promise Technology in general.Customer orientation seems seriously lacking.
