Unable to register and make payment for subscription

Hi, I am trying to buy the silver plan but can't do my registration. Appears this message that the daily  registration limits exceeded.can you help me? Thanks in advance. Adeir

Thank you for choosing JotForm. I have checked your email address and see that there are no accounts registered. Are you receiving any error message while you are trying to register the account? Could you share us the screenshot of the issue on this thread so that we can take a look and provide you with necessary assistance?

We will wait for your response. Thank you! 

This  is the message that appears when I try to register myself. When I click to send this email the message says my email is also registered. But I can't remember mu user name. IF I ask for a new registration the email is not sent.

To my understanding, you are trying to upgrade your account to the Silver plan.

I have searched the email address you're trying to use with your registration. I see there are two guest accounts associated with it and I have deleted both of it hoping that will solve the issue you're having.

Can you try to sign up for an account again, please? You can still use the same username and email since both are available.

If, by any chance, you can not still register, try clearing your browser's data or use a different browser.

Thank you.
