Embedded form: not working anymore

another issue I had, is originally I had this form embedded on our site...it worked fine for a while then would no longer work. I had to change to a link to your site instead of embedding on ours. 

First thing you could try is clear your form cache:

The link you are talking about may be the iframe code:
