The security key is originally programmed to allow you to perform 50 formulations, or edits to a composition. Once these have been used up, the security key will be disabled.
After payment, you will then be emailed a unique password to re-activate it.
To do this, run activate from the security key folder that was installed into your program folder. Under Nutritional Tools, check the box next to WinFeed, select ‘version 2’ from the list, enter your password, and click on the Activate button.
