edgelinux upgrade: antman won't start

I just did an fresh ISO install of EdgeLinux 2 from USB on my one. Followed the videos. Looking good, but running 'upgrade-antman' after install gets me what seems to be a license related error (see further below)? I've done upgrade-anthill as well, and that seemed to complete correctly. Have also tried rebooting. Nothing is listening on 3000 in 'ss' output, ergo can't visit it in a browser from my PC.

I did try putting my serial from anthill into that text file it's throwing a 'cat' error about, but that didn't do anything, so I reverted that change.

I opened a ticket for this as well but admittedly I am confused about licensing entitlements, so casting my net to the community forum as well.
