form update

I am having trouble getting the Mailchimp Signup form I created to update. If you look on my site you will see the background on the signup form does not fit in with my theme. I paid form the Premium Mailchimp in order to be able to edit the form so that it matches the theme better. Now I can not get the Mail Chimp Signup Form Widget to load the new version of the form. What am I doing wrong?
