Fahlgrenmortine We have also been suffering this problem for a week, but we found that not clicking the "I agree with evaluate license" option during checkout could jump through the generate license file process, instead it will show a download link at the license files block on the bottom left corner.
We tried this license file but it shows an error code of '-2' which indicates 'License is for another ISV'. Infact our license is maya-only and we deploy it in maya at the supported version, so we post an issue here in the community but no reply yet.
We also sent email to "support@zivadynamics.com" for support, unity suggests us that unity China support team would be able to help us so we sent an email to "support@zivadynamics.com", but no reply yet.
We are keep following this issue and will share any information might help once we get it.
