Product theme with multisite and buddypress problem

I am setting up a new multisite with buddypress. I installed product theme and I get the following error:

Fatal error: Cannot redeclare bp_dtheme_ajax_querystring() (previously declared in /home/ridgeroc/public_html/wp-content/themes/product/_inc/ajax.php:17) in /home/ridgeroc/public_html/wp-content/plugins/buddypress/bp-themes/bp-default/_inc/ajax.php on line 81

Also, before I got the error, I was able to begin configuring the Product Theme but it did not have the set-up tabs for BuddyPress.
