BuddyPress.org

Hello peeps just wondering if u can help me out. After doing a fresh install off buddy press it seems i can’t sign up new member profiles or any other component working i can enter by admin and set up new users but can’t register new users from the login or register page. I have followed step by step instructions but it seems it might have something to do with my permalinks. Buddypress installs with default url permalinks but when i was setting up buddy press it asked me to set up my permalinks. I chose php my admin but after setting up pages for buddy press which it asks u to assign a page to a catergory it seems the urls are the default permalink urls and not the ones for my site. My url permalink is http://localhost/xampp/wordpress/index.php/activity-streams/ The default set of links are:

Activity: http://localhost/xampp/wordpress/activity/
Members: http://localhost/xampp/wordpress/members/
Groups: http://localhost/xampp/wordpress/groups/
Forums: http://localhost/xampp/wordpress/forums/
Register: http://localhost/xampp/wordpress/register/ (registration must be enabled)
I have read so many turorials but none seem to point me in the right direction. Can someone help me out as i still can’t find an answer and i thought it was a simple plugin that worked out of the box
