BuddyPress.org

Yesterday I installed a fresh wordpress and then added some buddypress themes and then installed the plugin. Every theme but on worked fine but one was overlapped in certain parts by the default buddypress theme. I used a theme called Citizen Kane which worked fine but I had to re install everything and now the Citizen Kane theme is being overlapped by the default theme in places like the header and menu and causing certain areas to be displayed out of place. Is this familiar to anyone??
