A promotional code can only be used a certain number of times by each user, and only within a given time period. It may be that the code you have been given has now expired.

If you have not been given a code, but are using the pre filled in code on the website, this can only be used once per user.

If you would like to set up more ZygoHubs, please email support@zygocommunications.com and let us know what promotional code you are using, and we will issue you with a new one.
