[Plugin: Gengo] SQL errors

Hi,
In my server errorlog I am getting the following:

[Sat Sep 27 16:31:10 2008] [error] [client x.x.x.x] WordPress database error Unknown column ‘feed’ in ‘where clause’ for query SELECT language_id FROM wp_post2lang AS p2l WHERE p2l.post_id = feed made by locale

and

[Sat Sep 27 16:29:46 2008] [error] [client x.x.x.x] WordPress database error Unknown column ‘wp_posts.ID’ in ‘on clause’ for query SELECT wp_comments.* FROM wp_comments INNER JOIN wp_post2lang p2l ON wp_posts.ID = p2l.post_id INNER JOIN wp_languages l ON p2l.language_id = l.language_id WHERE comment_post_ID = ‘505’ AND comment_approved = ‘1’ AND p2l.language_id = ‘1’ ORDER BY comment_date_gmt DESC LIMIT 30 made by get_posts

whenever any page is opened. It appears this is caused by Gengo. Any ideas?
