captcha not showing

Hi Guys,

Just tried to install sweetcaptcha 3.0.6 on my site http://www.oceanhomeloans.com.au for comments only on the blog section of the site. The captcha doesn’t display and when a comment is entered I get the message that the captcha hasn’t been resolved. So the code is working but the capture in not being shown.

I am using Studio Press Eleven40 Pro theme with the Genesis 2.0 framework.
