John,
I added UE4 to your Limited Commercial License as well as extending your full trial (not sure which you're using right now). You should see the UE4 integration again. I really thought that you guys were subscribers, so you'd simply get the integration from Github.
As for UE4.6 support, we usually run 1-2 weeks behind Epic. If you get the new release notification emails, you'll receive something as soon as it's available.
Hope that helps!
