My form fields have disappeared - how to restore the form?

Suddenly, my form content is gone. Where did it go. This was a very, very time-consuming form to build. Please tell me what happened, and how I get it back.

Your form was somehow saved without the form fields. I would like to suggest reverting it to the previous version via Revision History.
