Error 28

OK so I upgraded to WP2 and I posted to it last night and everything was working and going fine. but all the sudden I get

WordPress database error: [Got error 28 from table handler]
SELECT DISTINCT * FROM wp_posts WHERE 1=1 AND post_date_gmt <= ‘2006-01-02 05:47:59’ AND (post_status = “publish” OR post_author = 1 AND post_status != ‘draft’ AND post_status != ‘static’) AND post_status != “attachment” GROUP BY wp_posts.ID ORDER BY post_date DESC LIMIT 0, 10

WordPress database error: [Got error 28 from table handler]
SELECT DISTINCT YEAR(post_date) AS year, MONTH(post_date) AS month, count(ID) as posts FROM wp_posts WHERE post_date < ‘2006-01-02 00:47:18’ AND post_date != ‘0000-00-00 00:00:00’ AND post_status = ‘publish’ GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC

WP can’t find any of my posts although the dashboard says I have 121 posts.

*sigh* what happened. I changed nothing. it just quit.

help please,
