Upon checking this form https://form.jotform.com/53133219240949, I'm unable to find it anywhere. May I know if you have deleted it purposely after reporting it?
I see that it is somehow a clone of an original form, could you try cloning it again and see if you are still getting the "Form not found" error? We'll wait for your response.
I see that this form is now in the "Trash" folder, you can restore it by following this guide: http://www.jotform.com/help/134-How-to-Restore-Deleted-Forms.
Let us know if that works.
