BuddyPress.org

Hi, i’ve installed buddypress on my website, but everytime i click on connect to wordpress it send me back to my website’s register page. so i went to wp-admin/options-general.php on my dashboard and changed the wordpress adress url to wordpress.org. now me and my members can’t log into their accounts, even when i go to the admin address for my buddypress installation on my website, i get redirected to wordpress.org. how can i solve this problem and change the wordpress address url on wp-admin/options-general.php back to the original address like it was. thanks
