Third party forms no longer display correctly.

Question

I inserted a form using code from InfusionSoft for a client and it displayed fine on the Muse page (not in the Preview or Design mode, but once it was uploaded it was fine).  That was on or about January 02. 
Today, January 05, I attempted to insert a form for another client using iContact.  The form just wouldn't display properly. 
After 2 hours of messing with it and testing it on other sources (WordPress, for example, where it displayed nicely), I decided to insert the InfusionSoft form from the first client into a test page for the second client.  Now, the form that worked before did NOT display correctly. 
Was there an update during this time that muffed this up on Adobe Muse?  I enjoy the product, and eagerly look forward to updates. In fact, Muse is one of only 3 products I really use anymore from the Creative Cloud package; however, I have to be able to easily insert forms.
Any advice, suggestions, comments, or compliments (yeah, I included compliments, cuz after 2 hours of non-billable frustration, I could use a smile).

After another hour or more: to fix the issue with forms not displaying correctly:
Upload the site to the host (even tho the form does not display correctly).
From the Cpanel's File Manager (or via ftp) go to
css folder
then to
site_global file
locate the lines:
body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,code,form,fieldset,legend,input,button,te xtarea,p,blockquote,th,td,a
          margin: 0;
          padding: 0;
          border-width: 0;
and remove the word "input," .
end.
