Guided setup keeps telling me there are no providers or channels in my zip code

If this is a repost, I sincerely apologize.

I have an old standalone Series 2 that I have not used in YEARS. So long in fact that the channel guide only had analog channels listed from the last time I had cable almost a decade ago.

When I recently opted to drop satellite (with which I had replaced cable), I dusted off the old girl and fired her up.

Since I no longer had cable and needed to add the digital subchannels, I decided to re-run guided setup. BIG mistake.

I put in my zip, the unit called in, and told me there were no local channels for my zip.

I tried a different zip for a larger city nearby that would have same channel lineup. Same result.

Heck, I tried a New York City zip and it could not find anything.

So then I told the unit had cable. Same result.

Then I tried satellite. Ditto.

No matter the zip code or the type of service I say I have, the Tivo mothership keeps telling me there are no channels for me.

And so I am stuck in an endless, inescapable, guided setup loop.

ANY suggestions on what to try would be hugely appreciated.

cheers
