recaptcha and moderation not working

Hi I have recently installed Komento and I am having difficulty with moderation. I am unable to moderate any comments even with "Enable Moderation" set to yes and the default "Requires Moderation" set to guest. Also I have set the recaptcha in antispam with the correct private and public keys, but recaptcha dose not display in the comment section. Here is the article/blog page with comments set up. http://www.digitalfracture.co.uk/blog/24-tech-tips/25-prevent-computer-theft-and-avoid-data-loss Moderation is set to public guest and recaptcha is in use. My Joomla! version, is 3.2.3. Any help would be greatly appreciated. Thanks in advance Dave.
