I had no idea anyone even bought the non-premium package. I bought the Cubs only package then realized it didn't include the audio or At Bat app. Rocket, I called them and if you log into the mlb.tv website you can upgrade for the extra $20 and it will give you the full premium package. That's what I ended up doing. Once you have the mlb.tv page open, at the top, there is a drop down that says 'Learn More'. If you click that, one of the options is upgrade. Why they would hide it there I don't know.
