TiVoHD running out of guide data (in a week)

First time this has popped up.......

Background:

TiVoHD with upgrade HD
Straight cable to TiVo with cable card. No tuning adapter in the loop.
Recently looked inside and all was fine

Connection Successful
Garbage Collection Date is fine (current)

Data ends in a week. If I go to Guide/Live I see it out further.

?: Apparently after I had rebooted my router/modem several days again the TiVo may not have been able to connect. I unplugged the TiVo wireless adapter and received a new IP. Connected to the service and it says everything Completed/Done......Could it still take a while for the data to index in the background? We are talking about a week's worth of data.....

I have rebooted a few times, connected successfully a few times, etc......

At what point do I try rerunning GS, if at all?

No sign at all of any HD or other failure. Everything looks fine.

Thanks ahead of time for help.
