Let's get your trial account cancelled, Nazbin.
Since you subscribed to the 30 days trial, you can either wait until it ends or click Cancel Trial to stop the subscription. Once your account is cancelled, there will be no charges since your billing information is not in the system. You will only receive a charge if you subscribe to a paid version.
If you wish to switch to a paid one, you can click the Subscribe now link beside the trial period. Then, enter your payment information so you can start using your account. If you'd like to change the version, you can visit our website and subscribe from there. The good thing about it is you can use the same log in credentials for all accounts.
I've added a screenshot too.
Please keep me posted if there's anything else you need.
