BuddyPress.org

I’m sure this is a simple fix, but it’s driving me nuts. I installed Buddypress and the template pack. I changed all the divs so the buddypress pages match the theme. Everything seems to be working fine except that the home page and buddypress pages are 100% width. If I navigate to a page like the about page it’s the original width of the theme. Can someone tell me what could be causing this or what file might be overriding the themes style.css. I’m using the latest version of buddypress and wordpress. The theme I’m using is mystique found here. http://wordpress.org/extend/themes/mystique
