Hi you should log into your Kindle account on your new device and just download your books from the cloud your books are available in your account once you have bought them you just tap on the book and it will download onto your new one

Books you buy on line go into your Kindle Cloud library. To get them onto your device, too, at the time of the purchase you must have your Kindle turned on and connected to Wi-Fi or Whispersynch which is another name for Kindle's 3G (cell phone) connectivity.

If you don't have your kindle listed as the default device, books won't automatically download to it. You will have to do it manually which means touching the Cloud on the home screen while connected to Wi-Fi or 3G and finding the book in your Cloud library. Touching the book will cause it to download onto your Kindle's local storage for anytime use.

When you buy a book it goes into your library. You can access Amazon Kindle via the Amazon website and check your library to make sure the book you bought is listed there. If it is not, then something went wrong and your sale didn't register. If your new book is listed in your library then it is available. Make sure your Paperwhite is connected to the Amazon Servers via Wi-Fi or 3G if yours has that option and touch (Cloud) you should see your new book listed in your library. Touch it and it should start downloading. It should not take long for the download to complete and the book to appear on your Homescreen. New books should automatically download the first time you connect to the servers after you buy it. But if they don't for some odd reason manually touching them will cause them to download.

That would be true for all your apps too.Your password should be the same for all Apple devices.
Book is paid for so download it to your iPad. You will never pay twice for any app,book, or music.

talk to customer service for KOBO. You may have bought a book in the wrong format for you reader. Also contact the place you bought the book from for a refund.

If you log onto your amazon account you should still be able to download the book again. Go to the shop section on your device or a web page and look at your purchases.

Coby sent this to me asking for my solution, But I'm the one who asked the question in the first place and I still haven't found or gotten a solution.
