This behaviour is intended and this is so the license server can be validated that your license is compatible with version 12 when you reactivate. You may also see this message after updating:
In order to start monitoring your servers you will need to activate a license that is within its support contract. You can easily check this by logging in to the Redgate Portal and looking in your account license section. Here you will be able to see if the license is support and if you are entitled to use the latest version with your license:

Please see the guide below on how to activate now:
If your SQL Monitor installation does not have a connection to the license server (For example if you are in a locked down environment without internet access) then please see the guide below on activating using the offline method:
