Tivo Won't Recognize Comcast Digital Economy Channel Lineup

I have a Series 4 (Premier) using a Comcast cablecard. I switched from Comcast Digital Starter to their Digital Economy package, which includes fewer channels. However, my Tivo doesn't seem to know this, and still thinks I have those missing channels. So it shows certain shows as available, and tries to record them, but instead records blank space. Same problem when switching through the channels watching live TV. It doesn't seem to get this info from Comcast, and I don't see anything in the Settings to change the package manually. I could go through all the channels and uncheck the relevant boxes, but channels lineups occasionally change and I would prefer not to have to somehow keep up on changes and check/uncheck the channel boxes accordingly. Can this be fixed?



Thanks!
