My TiVo Premiere is suddenly having issues. The "My Shows" menu is blank, other than the recently deleted folder. Across the top of the screen, there is a message that the tivo can't connect to the internet. When I try to go into other menus from tivo central, such as to reboot the tivo or check network settings, it just takes me back to the tivo central screen. We tried power cycling the tivo, but it came back up just the same. Any suggestions?
