I bought a Premiere about 6 months ago, and it's been working fine with Comcast. I moved, and switched to Charter service. The tech installed the new card, and it went through the M-Card activation. But the tivo is acting strange. When I boot, I get to the main menu, i go to enter setup to restart the guided setup, and it just keeps going back to the main menu whenever I try to enter the settings menu. From the main menu, i go to Messages and Setup, then go to setup, it thinks for a moment, then goes right back to the main menu. Account does the same thing. In fact, every sub-menu of the setup does the same thing. How can I reconfigure it if i can't even get into setup?
