No recent key request from you has reached us. Please make sure to send the request from the same mail address that used to register vorpX originally. Should only take a few minutes usually. The system does not reply to unknown mail addresses though.
If you are sure you have sent your mail from the right mail address, the mail did not go through for some reason. In that case use the contact from linked in the support menu. Messages sent that way have to be processed manually though, which will take a while.
BTW: You only need a new key if the request code shown in the license dialog has changed. If it’s still the same as before, your original key still works.
