Vista - easy transfer data link cable trouble

I bought an easy transfer cable from cables unlimited and it is not being
recognized by my windows xp system. Vista machine recognizes cable
immediately. The XP is a vaio laptop that has started having problems,
hence the new comp. But I did get the driver loaded, and it makes the new
connection sound, but nothing happens. At most, I've gotten a message
saying that the usb device is malfunctioning.

I called Cables unlimited, and they could not give me an answer, but they
did give me an email address. I am still waiting for a response.

What should I do?!?!

Thanks!
