Of course, not long after I posted this, it began working again! Maybe they did their maintenance earlier that scheduled, although doing it in the prime time wouldn't make any sense.
I hope it did some good, because Roku has been acting up recently, erratically. Sometimes a lot of channels in the guide will show No Information, or even from the homepage, I'll click on a channel, even the Roku Channel, and it'll flash, then take me back to the main menu again, and so on.
Oh, the most aggravating thing, is that every once in a while all my Favorites disappear!!
Then I must manually go through the process to make each one a Favorite all over again.
