Okay, so I've been using Google play forever and I love it, the music manager is cool too. But I recently have had a huge issue with the music manager that is very frustrating. All of a sudden, the music manager icon on the bottom right of my task bar where the notifications are disappears. I restarted my computer and it came back, but now every time I even put my cursor over the icon it disappears! every time! It doesn't upload any music anymore either. I've tried a lot of things to fix it, but nothing is working. Please help! My laptop is running windows 7, thanks!
