Submit button doesn't work!

I just bought Jux Testimonials with prof install
Made a menu with Jux Testimonial.
Choosing the menu Testimonials pops up inclusing a testmoinial i made at the backend
What doesn't work is the submit button
Nothing happens when clicked.

By the way whats the difference with or without the pro install? Can't see something special really!?
