help! wordpress gone wild

[HeavenlyCurves]

Okay let me start this off by saying it's a poor neglected blog I started for Heavenlycurves to replace out "whats new page" and we never converted it over to real time. so it's just been there on it's own trying to catch it all up bit by bit.
So the HX we changed servers a few months ago and now I finally had time to look at it and euuuuuwww this is what I see.


WordPress database error: [Can't create/write to file '/tmp/#sql_cff_0.MYI' (Errcode: 13)]
SELECT DISTINCT * FROM wp_posts WHERE 1=1 AND post_date_gmt <= '2007-11-14 22:42:59' 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 10, 10

Can anyone tell me in "blonde" terminology what happened and is there a way to fix it without losing all my history?

thanks so much for your time.
