Refractive handles purchases manually, and currently they have a lot of purchases. In addition they are moving to a new office, so all this results in a lag in activation of new licenses. Please, be patient a little more, I'm sure they will get to you soon. When you will be registered as a licensed user (you are currently not, even if you are able to acces your account on the site), you'll be able to download the latest release from the "Commercial Product News & Releases" forum, that will become accessible.
