Contact FORM not Working

Hi,

My contact Form in JellyBean 2.0 with Wordpress 3.4.2 does not work. No mails are sent.

You can view it here:

I've added the contact Form 7 plugin to check mail function and it works.

I checked the spam folder just to make sure that the messages were not going in there, and they were not.

The contact page seems to be sending the messages, I'm not receiving any type of error message when I hit the submit button, the page just reloads.

Regards,
