Registration is through PayPal. Upon completion of your transaction, you are redirected to a Breaktru Software Web page with a link to a document (.doc) which has the registration key. Simultaneously, an automatic email is sent with the same link to the registration document.
A small number of customers have said that they did not see the link. Perhaps they did not have a way to read a document file. If this occurred to you, send me an email to mail@breaktru.com and I'll manually send you the registration.
Also:
Make sure that the email was not blocked by your Internet Service Provider or Spam Filter. Check your Spam Folder because the manually sent email will not be received.
