Hi,
of course you are not doing anything wrong; The update i submitted to Epic for 4.7 is still not through on the marketplace unfortunately.
I would ask you to send me the receipt you got from Epic to my support mail address as a proof you bought it (we as content providers still dont have any access to this information from Epic), and i will send you a download link for the current versions of the Toolkit.
Thanks for your understanding!
Cheers,
