Can't find SVP4 Pro Download Link

I am an indigogo backer and am trying to reinstall svp after a factory reset.  However, it seems to be impossible for me to actually find and install the full version. I can find the free version, and a paypal link to pay for the full version, but no download link. Can any one point me to where I need to go? I tried logging into the wiki(i'm not sure if I am supposed too) to no avail.
