Unfortunately the mail address you used to register here isn’t in our customer database, so I can’t really check what is going on.
If this hasn’t been resolved already, please make sure that your mail contains the request code that is displayed in the license dialog and also send the mail from the same mail address that you used for purchasing vorpX to avoid delays.
If both conditions are met, and you still did not receive your key, please report back here and/or contact us with a second mail address in case there is an issue with receiving mails from your normal address.
