It’s important to include some details so we can track your order.

Please make sure you provide the email address you used to purchase the book. Don’t forget the name of the book either.

The transaction I.D. would also be helpful but not necessary. A brief description of the problem will help.

If you have simply failed to download the book in time, we will simply reactivate the download link for you.
