Hi, can you provide a bit more detail? What are you seeing that makes you say it just stopped? Are you getting a "Form Closed" message when you try to go to the form to fill it out? Did/do you have a Free or a paid account (does not affect our support level, just helps understand the issue)? Are you sure you are signing in with the same AdobeID you used to create your form/s? Are you embedding one of our forms into your website?
I'll be happy to assist further...
