Resolved Question: How to change Wordpress MySQL database setup from auto to manual on Blog Colony?

I mistakenly chose the automatic setup option for the Wordpress MySQL database setup when I added a blog at Blog Colony. How will I change it to manual so I could use the MySQL database from my host? I tried editing the wp-config.php file, but the blog contents are not showing up so I restored the original wp-config.php file. Help urgently needed pls. Thanks!
