Because i clicked that it didnt work...
I installed it and the form appeared, but with some serious styling problems. I know for SURE they weren't coming from my site's style sheets or other plugins. I proved this by taking the embed code and adding my own styling - that worked ok.
The plugin added over 500px crazy spacing on the top it's container div ( somehow it's height was being calculated incorrectly and i couldn't comabt it with css ) .. also the fragments of text in the fone number field should have a span or something around them - they don't so they were impossible to target in relation the the form fields for the phone number.
the list goes on.
