i need help with corona render button

[quang_nam]

I bought a used corona key, got this error and can't continue working
I want to ask if my 1 key can be used for 2 devices?
I logged out and back in but corona still gives me an error and can't work

You have one license so one machine at any given time could work with it. Make sure you don't try to use it on two computers at the same time or you will get that error.
