Unknown column 'forum.tid' in 'field list'

Hello!

I have this current (very basic) setup:
Container 1
-Forum 1
--Thread 1
--Thread 2

When attempting to view Forum 1, I get the following error:

user warning: Unknown column 'forum.tid' in 'field list' query: SELECT DISTINCT node.nid AS nid, node_revisions.teaser AS node_revisions_teaser, node_revisions.format AS node_revisions_format, node.title AS node_title, history_user.timestamp AS history_user_timestamp, node.created AS node_created, node.changed AS node_changed, node_comment_statistics.last_comment_timestamp AS node_comment_statistics_last_comment_timestamp, users.name AS users_name, users.uid AS users_uid, node_comment_statistics.comment_count AS node_comment_statistics_comment_count, node.type AS node_type, node_counter.totalcount AS node_counter_totalcount, COALESCE(ncs_users.name, node_comment_statistics.last_comment_name) AS node_comment_statistics_last_comment_name, ncs_users.name AS ncs_users_name, node_comment_statistics.last_comment_uid AS node_comment_statistics_last_comment_uid, node.sticky AS node_sticky, node.comment AS node_comment, node.sticky AS topic_is_sticky, forum.tid AS topic_actual_forum FROM node node INNER JOIN term_node term_node ON node.vid = term_node.vid LEFT JOIN node_revisions node_revisions ON node.vid = node_revisions.vid LEFT JOIN history history_user ON node.nid = history_user.nid AND history_user.uid = 4 INNER JOIN node_comment_statistics node_comment_statistics ON node.nid = node_comment_statistics.nid INNER JOIN users users ON node.uid = users.uid LEFT JOIN node_counter node_counter ON node.nid = node_counter.nid LEFT JOIN users ncs_users ON node_comment_statistics.last_comment_uid = ncs_users.uid AND ncs_users.uid != '0' WHERE (node.status <> 0) AND (term_node.tid = 104) ORDER BY node_sticky DESC, node_comment_statistics_last_comment_timestamp DESC LIMIT 0, 20 in E:\Inetpub\wwwroot\modules\views\includes\view.inc on line 771.

Neither of the threads show up, and everything works OK without Adavanced Forum enabled.

Thanks
