When an eBook protected with Secure-eBook is opened for the first time, only the sample is displayed. The eBook will have to be activated in order to get access to its full content.
To activate the eBook, you need an activation key which you can obtain from the eBook's publisher.
After you complete the purchase transaction, you will receive an activation key. That's the key you will use to activate the eBook.
If you purchased the eBook without using the “Buy This eBook Now!” button or if the activation window is not displayed, just select “Activate eBook…” from the “eBook” menu. If you did not get the eBook yet and do not know where to download it from or how to get it, please contact the eBook's publisher.
When the activation window is displayed, copy (Ctrl-C) your activation key from the email you received or from the Web page where it was displayed, and paste it (Ctrl-V) into the activation window. Then, click on the “Activate” button to get access to the eBook's full content.
If you have problems opening your eBook protected by Secure-eBook or did not succeed in activating it, please visit the eBook Activation Assistance page.
