I have a HTC Incredible 2, 3G. Every time I open my Play Books app to start downloading books/reading them, I get this notification: "Couldn't retrieve Google Play books library from Google. Check your internet connection and try again." My WiFi works perfectly and is always connected to either my home or work internet. Also, out of curiosity, I turned off my WiFi and tried. Gave me the same message. So now I'm stumped. Any suggestions/answers? Keep in mind, I am not very knowledgeable with smartphones and their software, etc. lol. Thanks!
