I have checked your account and found that you're asking for Credit Card info in your form http://www.jotformeu.com/form/62283504866360
Here is a screenshot of the guilty fields:
Asking for Credit Card info goes against our terms, I would suggest you to read it as there's stated what you can and cannot ask on your forms: http://www.jotform.com/terms/
I had to remove those fields from your form in order to re-activate your account, please avoid keep asking for this info, otherwise your forms will be disabled again.
If you need to collect payments, please do it through our current payment integrations, here is a guide about it: Order-Form-Basics
