When your license has expired, it would be great if you have the ability to update this via the K2 Management UI instead of having to run this via the K2 Configuration Manager or updating it directly in the K2 Database.

Below it would be better for users if it said:

Expired License

Your license has expired, please enter your new license key that you have received from portal.k2.com

Enter your new license key: xxxxxxxxx

[Update Button]

With it pre-populating the machine key, it would make it easier than the current system of having to reach out to a K2 support representative.
