Form submit not sumbitting

Hello,

I have had the following form for years, and it has always worked, until about a year ago when Google took over Captcha, or whatever happened in that arena.

https://www.lh-productions.com/av/?page_id=10

I’ve managed to update my Captcha keys, but the emails still disappear into cyberspace, i.e. I never receive any of them. The form submit page came with my AV 1.0 Theme. This is currently what’s displayed on the Contact Page Template. There is also a ajaz.recaptcha.php, as well as a recaptchalib.php

I am not a designer, just had to take over after the guy I hired to do WordPress dropped off the face of the planet. Any direction is appreciated.

Thanks!
