All of my forms are disabled. How can I fix this?

We do not allow for the collection of credit card details through forms.  Your gift certificate form requested such details and it resulted in the account being suspended.  As per our terms of use:

Collecting Sensitive Information. You may not use the JotForm to collect certain types of sensitive information, including but not limited to credit card information and any type of login credentials. You may collect some sensitive information such as social security numbers or driver’s license numbers, but you are required to use best security practices of JotForm including SSL and Encrypted Forms features. You are solely responsible for compliance with any data protection and privacy laws and rules applicable to the sensitive information.

We have recently needed to become much strict on this due to becoming PCI compliant.  This required removing any currently stored credit card data from our system. 

If you require payment authorization, that can be done through one of our many payment processors:

I removed the offending fields from the form and activated your account.  Your forms should be usable once again.
