BuddyPress.org

I have the exact same problem as cristina.
running wp 3.0.1. on localhost (using WAMP to run it) with several different BP enabled themes (I blamed the themes at first) but no matter what the theme the permalink structure and the Buddy press seem to collide giving me the ever popular “Not Found The requested URL….was not found on this server.”

I am not very computer literate. The htaccess file is in the root
# BEGIN WordPress

RewriteEngine On
RewriteBase /wordpress/
RewriteRule ^index.php$ – [L]
# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*.php)$ $2 [L]
RewriteRule . index.php [L]

# END WordPress

But what I am ever going to do with it?
index.php is also in the root and like .htaccess I have no idea what it says in it.
<?php
/**
* Front to the WordPress application. This file doesn’t do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define(‘WP_USE_THEMES’, true);

/** Loads the WordPress Environment and Template */
require(‘./wp-blog-header.php’);
?>”
