All of our digital methods and some of our books and teaching materials work with a license code. This code gives you access to all or additional teaching materials.
When you buy a book with a license code, you will find this code at the beginning of the book. When you purchase a license code for a digital product, you will receive an e-mail with the license code within half an hour after placing your order.
Did you not receive the code or is the code not working? Please contact our customer service.
The license codes of digital products or sites can be activated up to 18 months after purchase. The license itself states how long you can work with the license from the moment of activation (two weeks, one month, six months, year).
The license codes in our books are valid for one year after activation.
