Am no longer able to get in to the designer?

I keep getting this error ...

You are not authorized to edit this form.

I am using the admin login so I can't imagine why I would not be able to access the designer. I want to change the color of the submit button on this form to black - http://form.jotformpro.com/form/52588645059973

Generally, this error appears when there is no active session while trying to edit the forms. This may also happen when different domains are used. Please make sure that you are logged into your account using http://www.jotform.com and then try using the link below to edit the form.
