I just bought a new lap top what has windows vista. I also upgraded to the new cable. I installed the program and then it wanted me to hook up my interface and so I plugged it in. Then windows reconized it and started installing the driver for it but then canceled becuase the driver does not have a digital signature and windows vista requres it. My hp program will not reconize it now. What do I do? I need to use it asap. Thanks for the heip.
