Hello JoaoSaude,

I'm sorry for the trouble caused to you.

Do you get any error message when you input your credit card details? Can you please share a screenshot of the payment screen what you see? The following guide should help you how to upload image in forum post:  http://www.jotform.com/answers/277033 

I would suggest you to please sign out form your account and then sign in again before attempting to upgrade your account again. 

We will wait for your response.

Thank you!
