I just installed the new Spotify Channel on my Roku 2. Everything started out fine -- installed properly and initially played ok. Then the Spotify channel went into a screensaver mode (not the RoKu screensaver; this is particular to the Spotify channel). Now, i can't get out of the screensaver mode. I have tried pressing every button on the controller; I have exited the channel and reentered; i have rebooted the Roku box; i have uninstalled and reinstalled the Spotify channel. Everything has failed. When I go back into the channel, the screensaver mode starts, with no sound or ability to do anything.  Anyone else having this problem? Any fixes?
