I just renewed my Membership on Apples Dev Site, and now I'm trying to update to macOS Sierra - went to the Dev Download Site, redeemed my Download Code via the Download Button and started to download the Update, but had to disconnect my Internet-Cable. But now (of course, after reconnecting the Cable) the download isn't working anymore. I tried to restart my Computer, removed all Caches, even resetted my NVRAM, but I'm still stuck on that:
PS: I am in El Capitan Beta 15G12a
