Hey,

the trial license is valid for one month. You need to [purchase a subscription](https://www.elastic.co/subscriptions/) in order to get another license. See the [watcher docs](https://www.elastic.co/guide/en/watcher/current/license-management.html#license-management).

I am happy to get you in contact with our people, if you tell me where you are based.
