'wp_m_membership_news' already exists

I got this error message:

WordPress database error Table 'wp_m_membership_news' already exists for query RENAME TABLE wp_membership_news TO wp_m_membership_news; made by loadWordpress, initWordpress, require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), do_action('init'), call_user_func_array, membership_news_install, membership_newsstreamcreatetables

What do I do?
