I have a classic licence for 2020 and run 2021 now from that. I need to run 2020 again, for in there vray 4 licence is installed and I do not need to upgrade vray. Chaos seems to refuse to make vray 4 available for 2021.
But my 2020 is wanting a licence again (which i do have) but it does not accept the codes, which it should, because it is perpetual.
What is the issue here?
