Get rid of empty sidebar?

Hi
love the plugin – thank you! I also bought one of the add ons to make the page my home page..

My only issue is that I want a landing page/squeeze page without a sidebar distraction.. But the empty sidebar on the landing page makes the header image and the body text stay left aligned (http://www.twodaydiet.info/)
Is there a resolution for this?
Thanks
Dave
