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 firstname.lastname@example.org
and I'll manually send you the registration.
Make sure that the email was not blocked by your Internet Service Provider or Spam Filter. Check your Spam or Junk Folder because the manually sent email will not be received.
Also be sure that the email address on file with PayPal is still valid.
