Has anyone an idea? My Wife was using her Nook HD+, after the update to include Google Play and, somehow, the Play Music app / icon vanished off of her system. She didn't tell me right away, but kept downloading the app from Google Play. It would say it was installing, but didn't show up. So, she has everything, but the Play Music on the machine. I'm not certain what to do with it. Had she said something right away, it might have just been an icon issue. Somehow, this is my fault. HELP!
