Hi,

Sorry for the trouble.

Can you please send a ticket describing what is the issue you are having there, too, with this link:

I don't think it is Corona related, so Tech Support colleagues will proceed with you.

Hi
While you were writing a reply to my post, I also formatted my computer. After this process, everything works. If anyone has the same problem, I recommend formatting your computer and then checking your license on the Chaos Licesne Server website and logging in there. the error may be caused by the fact that you once tried a version of the Corona or V-ray engine and the servers think that you do not have a new license.
Greetings to everyone and thank you for your response

I am glad to hear that the issue is solved, but I don't think there was any need to format the whole PC :)

This is usually related to the browser cache and cleaning it should have solved the issue for you.

Nerevtheless, in such cases it is recommended to submit a ticket. That way the issue will be address more effectively.
