Corona ask for report: Corona licence is required for this operation. Just trying to render at fresh install. What next?
Did you installed corona with the installer?
Did the intaller told you the license was correctly acquired?
Do you have some firewall?
I had a node in my farm that wasn’t able to acquire a license, but it was a windows problem, I had to reinstall windows to fix the problem, it was affecting more things, not just Corona.
I hope some of this helps you.
Cheers!
My guess is: did you change system time recently?
Thanx corona brothers!
Keymaster was right, just wrong time.
hahaha of course, this was another problem in another machine with a bad mb battery 
Cheers.
