W_ADEPT_CORE_WRONG_DEVICE

This error message typically appears if the book owner only allows the book to be downloaded on one device. Also, the download takes longer if the file is too big and your device has limited space to store the whole file. Network connection speed also matters.

 

To resolve this, we suggest you contact the book owner/vendor directly from where you purchased the book to see if they can give you access to another device.
