We're running the latest APM and NPM, and since I first installed them, we've been through several upgrades. Our annual maintenance was recently renewed, and shortly after I received an email saying that our APM was unregistered and needed to be activated. I don't remember having to go through this with recent versions. I see the activation key, but it says to click Activate, and I'm not sure where I should be looking. I don't see an Activate button. Can somebody help me?
