In 2015 I bought a Confluence server starter license for ten users. I stopped using it long ago. Now I want to use it in the latest release of Confluence, but it shows me an invalid license error.
I would like to know why this happens. Is this because it is a starter license? Is it because I am trying to install a release which is later than the expiry date of my license? If so, what is the real meaning of "perpetual".
Thanks for your help.
