WordPress Crashed – Error_log

Overnight, my WordPress crashed (when you got to http://www.raymondfong.net all you see is
Page not Found

We’re sorry, but the page you’re looking for isn’t here.

Try searching for the page you are looking for or using the navigation in the header or sidebar
)

I checked my error_log file and it shows a whole bunch of messages pertaining to wp_posts such as this:

[13-May-2009 07:38:05] WordPress database error Table ‘./ironhell_wrdp1/wp_posts’ is marked as crashed and should be repaired for query SELECT * FROM wp_posts WHERE ID = 54 LIMIT 1 made by require, require_once, include, get_header, locate_template, load_template, require_once, wp_head, do_action, call_user_func_array, iThemesFeaturedImages->initImages, iThemesFeaturedImages->_fadeImages, wp_attachment_is_image, get_post

What’s going on? How do I fix it? I have the plugin http://ww.wp.xz.cn/extend/plugins/bb-login.php installed (so luckily I have yesterday’s DB backed up) should I just restore using that tool?

Please help, thanks.
