Need to change title link in Headway theme

Hi,
I have two problems, but the first being the most pressing. I am a photographer that uses Photoshelter theme for my main site, but I like wordpress for my blog. They have an integration feature, but it’s super limited, so I still want to keep the main site from my blog.

Main site: dhbrownphotography.com
Blog: dhbrownphotoblog.com

What I need fixed ASAP, and I haven’t been able to find ANYTHING on forums, is how to change the default link of the title of the blog. It defaults to dhbrownphotoblog.com. I want it to go to dhbrownphotography.com.

In the visual editor I have found the .php code for the title, but I can’t find anything that says .
And in the header.php section it says:

<?php
/* Prevent direct access to this file */
if ( !defined(‘WP_CONTENT_DIR’) )
die(‘Please do not access this file directly.’);

HeadwayDisplay::html_open();

wp_head();

HeadwayDisplay::body_open();

Any information is much appreciated!! Thanks.
