I have a TiVo HD (lifetime service, WeaKnees upgrade, uses a Tuning Adapter) which was unused for a few months. Of course, when I hooked it up again it had no current program information. However, when I connected to TiVo, no program information downloaded. I thought there might have been some change with my provider (Time-Warner), so I ran guided set-up again. This time it did download the approximately 2 days of program information which it ordinarily gets in guided set-up, but a forced connection thereafter still does not get new program information. The connection works, it goes through all the steps, but nada for info. The only error message I get is the dreaded "Program info will run out on Mon 5/13!" The unit appears to behave normally in all other respects.

Any guess as to what might be happening and how I can fix it?
