The ‘news’ button only works if the home theme is running on blog id 1. Sounds like it isn’t. You have to hack some stuff to get it to work. If you are comfortable changing the code in the home theme then it’s here:

if ( $current_blog->blog_id > 1 )

return false;

lines 59/50 in themes/buddypress-home/functions.php. Comment those out and news works.
