Hi Seymour,
I've been running an HDHRPrime on Time Warner Cable for a while now, and I had the same issue when I was setting it up. The short version: the channel scan doesn't work, but you don't really need to do it. If the card is activated, it will "just work" from your media center app. Which are you using? I went with Windows Media Center running from a computer with Windows 7 Professional. Once you've gone through the activation sequence for CableCard and downloaded the guide, it works pretty well.
Shoot me an email if you have any specific questions and I'll try to answer them.
Mike
