Neither of my TV Minis will allow me to play music (via Pandora) by selecting 'Music and Photos' from the main Tivo menu. As soon as I highlight the 'Music and Photos' menu option, a blue screen appears with the following message: Unexpected Problem There was an unexpected problem. (C501) It seems this issue started happening within the last 2-3 weeks. Has anyone else experienced this problem and if so, how did you get it resolved? Thank you.
