Log on to crowdfireapp.com and click on your plan right on top (it will be a button with your plan's name). In the page that opens next, unsubscribe from your current plan by clicking on Unsubscribe below that plan. Once the unsubscription is complete, return to the pricing plans page. Click on Upgrade below the account you want to upgrade to and make the appropriate payment.
That’s it, you’ve now been upgraded. Time to partayyy!
