I let my pro license expire and have recently upgraded to a different license now and put in my new license key, but the update still says that it has failed. I still have the User Role Editor plugin installed, but not activated at version 4.31.1, but my User Role Editor Pro plugin is at version 4.23.2.
If you did not register new account, but upgraded your older account, the license key is still the same. Update server caches responses for 6 hours. I cleared its cache. Try again. You should receive a response according to the actual state of your license key.
