When I checked your jotform http://www.jotformeu.com/form/51414449866362 I could not see any fields on it. There must be issue with the Form Builder.
You can restore your form to the working version using the Revision History feature.

There was a problem on the Form Builder this week. That might have caused this.
If the form wasn't probably loaded on the Form Builder and then saved while it was empty, that probably caused the elements to get lost.
Luckily we have the Revision History that can be used on such cases.
Hope this help. Please let us know if still not resolve.
