When I use "category__not_in" it works - but the query is reversed.
$args = array ( 'post_type' => array( 'post' ), 'post_status' => array( 'publish' ), 'category__not_in' => array( 74, 77 ), 'posts_per_page' => '6', 'paged' => $paged );
Maybe anyone had the same problem before and has a tipp? ("order" and "orderby" does not help)
EDIT: I misunderstood something, I have to use "post__not_in" instad ;)
