Typically, if books do not load, it could be one of three issues.
- The program has frozen. This usually happens on devices with less memory and on books that are very long. Open the android settings and go to the apps list. Select Blio and tap the force stop button. Then reopen the app and see if the book will load.
- The version of Blio is out of date. Check the Play store to download the app update.
- There was a failure to license the book.
