Thank you for contacting us. In these cases, the only option is to cancel your subscription on your old Apple account, if you haven't done so already, then sign up for a new one on your new Apple account. Unfortunately, Apple doesn't give us the ability to move subscriptions from one Apple account to another, and I don't believe they will do that for you either, so the only option is to cancel and resubscribe.
Real quick, before we do anything else, when you open mSecure and check your Account Settings, does it show you have a Premium account still? It looks like you have a monthly subscription, and that it expired on January 4th, but there is a grace period before the subscription will be expired in the app. Also, did you cancel your mSecure subscription before moving to your new Apple account?
