You should install BuddyPress along with a BuddyPress supported theme.http://themeforest.net/item/cinematix-buddypress-theme/4959387
Sometimes it takes a while to find a theme that fits your website. So, take your time, we’re not going anywhere.
What software are you running?
Have you checked the creative category for ThemeForest themes?http://themeforest.net/category/wordpress/creative
I would deactivate the plugin until the bug is fixed. Also, have you tried contacting the plugin author about the error?
I like the idea.
