card reader challenges

I have the vista system on my new dell computer. I'm trying to use my sandisk
sddr-09 usb smart card reader. According to sandisk it is system ready
without a driver. But my computer tells me I need a driver. The closest
driver from sandisk is the windows 2000 driver but when I load it I am given
file error message. The guy at sandisk tells me I need to contact Microsoft.
When I tried ot access via website and typed in my procut serial number for
viata it tells me I've done it wrong. I've checked the numbers twice and re-
entered to no avail now what?
