ReCaptcha not working

Using the code below the recaptcha is not visible on page and does not allow contact form to be sent. When I remove recaptcha, the form works fine. I know it is setup properly because I am using recaptcha in other plugins and it works fine with those. Any help is appreciated.

<p>Your Name (required)
[text* your-name] </p>

<p>Your Email (required)
[email* your-email] </p>

<p>Subject
[text your-subject] </p>

<p>Your Message
[textarea your-message] </p>
[recaptcha]
<p>[submit “Send”]</p>
