Anonymous users cannot view Image Galleries when Simple Access is installed

Simple Access works very fine on my website (4.6.8), but the only thing that doesn`t work is: Anonymous users cannot access the image galleries (that come with the image-module). They get the following error when they try to open one:

Fatal error: Unknown column 'n.nid' in 'on clause' query: SELECT t.tid, COUNT(DISTINCT(n.nid)) AS c FROM frightening_term_node t INNER JOIN frightening_node_access na ON na.nid = n.nid , frightening_node n WHERE (na.grant_view = 1 AND CONCAT(na.realm, na.gid) IN ('all0','simple_access0')) AND t.nid = n.nid AND n.status = 1 AND n.type = 'image' GROUP BY t.tid in C:\Programme\xampp\htdocs\frightening\includes\database.mysql.inc on line 66

When the user is logged in, he can view the image galleries. When I disable the simple access completely (of course correctly with the given instructions) the image galleries also work for anonymous users.
