UDesign Dropdown menu problem

Hi,
I am in the process of updating a website to an SEO friendly version, which is why I chose Udesign. I got pretty far along and everything was functioning just fine until this past week; my dropdown menus stopped working.
The only variables I could think of were:
a recent update of WP
a recent update of udesign
a couple new plugins (of which I have deleted to find the problem)

It works when I change the theme, But I really like/ want udesign.

Some research of forums suggested I check my JSON support on my server and that is not an issue.

I am lost! Can someone please help!
Thanks, Jack
