I installed the new update. Now, when I go to Music Player to listen to school book in my playlist, I have all the files, but when I click on them, I hear "audio player, and no sound. I updated to version 2.1I tried a re-boot. Then I tried removing the battery, replacing it, and still, I have no recordings on any of the files. Do I need to reinstall the Books? What will happen if I have my Icon revert back to the version previously in use? Did anyone else have this problem after updating to the new version?
