A registration key has been sent out to you immediately after making your purchase. It is an automated process and I even have a copy of the emial here.
The problem is most likely that you or your ISP have a spam filter in place that incorrectly filters out the registration email because it contains the manual as an attachment.
Please contact us at support@g3studios.com with an alternate email address if possible and we will send out registration information to you once again.
