I have a similar problem. I bought this product long ago. I had a Vista (stupid) and converted my daughter's 8mm tapes to computer. It was sweet. Then packed everything away with the camera and forgot about it. I have, today, been tasked to convert a couple of VHS HS football games for a recruiter. Fortunately, I found the hardware, but cannot find the software CD. I found the site you linked earlier to re-download the software, but do not know the order number of my product as I did not purchase it online, but at Best Buy. Any suggestions would be greatly appreciated.
Oh, and the Roxio site shows my purchase also.
