Organic Groups

Hello,
I don't know why, but just can not install Organic Groups.
Everytime I do it, all goes fine, I set up group node and group post,
and make the group node.

It works like it should, I can also see the new (and all) my group in /og/my
but when selecting /og - list of all groups, I see an error:

user warning: Unknown column 'n.nid' in 'on clause' query: SELECT node.nid AS nid, node.title AS node_title, og.og_description AS og_og_description, users.name AS users_name, users.uid AS users_uid, (SELECT COUNT(n.nid) FROM node n INNER JOIN og_ancestry oga ON n.nid = oga.nid WHERE n.status = 1 AND oga.group_nid = og.nid) AS post_count, (SELECT COUNT(*) FROM og_uid ou INNER JOIN users u ON ou.uid = u.uid WHERE ou.nid = og.nid AND u.status > 0 AND ou.is_active >= 1 AND ou.is_admin >= 0 ) AS member_count, node.created AS node_created, og.og_selective AS og_og_selective FROM node node LEFT JOIN og og ON node.nid = og.nid INNER JOIN users users ON node.uid = users.uid LEFT OUTER JOIN tracknstack tns ON tns.nid = n.nid WHERE ((tns.nid IS NULL OR tns.closed = 1)) AND ( (node.status <> 0) AND (node.type IN ('story')) AND (og.og_directory <> 0) )ORDER BY node_created DESC LIMIT 0, 90 in (...)/sites/all/modules/views/includes/view.inc on line 765.

I can not solve it. I was browsing the internet for answer, many forums but just can not solve that.

If anyone experienced could install views, og and tell me what to do to get /og working, I would really appreciate it.

Thanks,

Dave
