On your Roll20 Account page ( <a href="https://app.roll20.net/account/" rel="nofollow">https://app.roll20.net/account/</a> ) on the right side, you should see a section called Account Type & Subscription: On the subscribe page ( <a href="https://app.roll20.net/why-subscribe-to-roll20" rel="nofollow">https://app.roll20.net/why-subscribe-to-roll20</a> ), select "Pay Every Month", then click "Select Monthly Pro": Fill out a valid credit card or choose the paypal option. Roll20 is a Subscription. If you only want it for 2 months, you'll need to change your subscription after that period elapses. Hope that helps. If you have any trouble, you can email <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a>.
