Maxwell Render | Official public forum

hi all. I'm trying here as NL support are on vacation or something. Re-installed windows on one of my computers to find out I can't re-activate it as a render node only. Firewall is off, did all needed on the portal etc., still license activator says it can't connect to the server and Maxwell is not licensed. Made sure RLM is on, downloaded the license again, tried all sort of "allow" etc. on security, still not licensed. What's next? it sucks as I usually use the weekend for long high-quality renders...
