Error in wp_posts.MYI

I’m getting this error on all my wordpress pages, and my admin panel. Does anyone know how to fix this? I did display the main page on my site, but you can see it at

Thanks for the help!

This is the error message I’m getting:

[Can't open file: 'wp_posts.MYI' (errno: 145)]
SELECT ID, post_title FROM wp_posts WHERE post_status = 'publish' AND post_date_gmt < '2006-04-11 19:41:21' ORDER BY post_date DESC LIMIT 5
