Error 28

After posting my first article in my newly installed blog I got the following error:
“WordPress database error: [Got error 28 from table handler]
SELECT * FROM wp_posts WHERE 1=1 AND (post_status = “publish” OR post_author = 1 AND post_status != ‘draft’ AND post_status != ‘static’) GROUP BY wp_posts.ID ORDER BY post_date DESC LIMIT 0, 15″

Could anyone explain me what I did wrong or what is wrong with my configuration??
Thank you very much!
