Once you have setup a subscription to Shadow from http://shadow.tech it will then take a little time for the activation to complete.
This time can vary from a few hours to a few days. This delay is because your machine must be installed and configured with a single Windows license to make sure you have the best possible experience from the moment you begin.
Reducing these activation time delays is something we're currently working on
When your activation is complete, you will receive an email informing you that your Shadow is now available. Be careful to check your spam and trash folders to make sure it has not been redirected there by your mail service.
