installed bb press and it mucked everything up – need help

Hi Lee,
I went into the public file directory in my ftp and deleted any folder that started with bb_ which seemed to be the advice online. But there is a index.php page in the public files with the following code which seems to be what the error message refer to. All the other wordpress files are still there and I haven’t deleted any of those, I just don’t know how to get them to be what my homepage points at instead of anything referring to BB. I hope that makes sense. Probably not ……
I can’t list the file I deleted as there is no deleted files folder on the ftp for me to refer to – unless you know how?

<?php

require(‘./bb-load.php’);

bb_repermalink();

$bb_db_override = false;
do_action( ‘bb_index.php_pre_db’ );

if ( isset($_GET[‘new’]) && ‘1’ == $_GET[‘new’] ) :
$forums = false;
elseif ( !$bb_db_override ) :
$forums = bb_get_forums(); // Comment to hide forums
if ( $topics = get_latest_topics( false, $page ) ) {
bb_cache_last_posts( $topics );
}
if ( $super_stickies = get_sticky_topics() ) {
bb_cache_last_posts( $super_stickies );
}
endif;

bb_load_template( ‘front-page.php’, array(‘bb_db_override’, ‘super_stickies’) );

?>
