Cannot Log Into WP Admin

I tried to open our blog today, located at http://development.meritsolutions.com/matters/. The blog did not work, and told me to “repair” the database. After installing the Repair Code on our WP Config file, and attempting to repair and optimize the databases, I was shown these errors:

wp_usermeta: 5 clients are using or haven’t closed the table properly
wp_posts: 9 clients are using or haven’t closed the table properly
wp_comments: 19 clients are using or haven’t closed the table properly
wp_options: Table is marked as crashed
wp_postmeta: 7 clients are using or haven’t closed the table properly
wp_terms: 6 clients are using or haven’t closed the table properly
wp_term_taxonomy: 6 clients are using or haven’t closed the table properly
wp_term_relationships: 6 clients are using or haven’t closed the table properly

Now at least people can read the articles again… however, I can’t get into the admin site. Any help would be greatly appreciated!
