In a Dynamic Flash Gallery template like this, sometimes you might get into a problem where you couldn't receive message from your Contact page. Make sure that your hosting company supports PHP and mail post.
Check the file attributes of contact.php, it should be 777.
Make sure to set the correct recipient in form05configuration.xml. And you type PHP as the Server Processor Type.
That should be it. Try your contact form and you should be able to recive messages now.
