wlevar,
The following code will help you. It's from the wp-config.php file.
// ** MySQL settings ** //
define('DB_NAME', 'wp_name'); // The name of the database
define('DB_USER', 'name'); // Your MySQL username
define('DB_PASSWORD', 'password'); // ...and password
define('DB_HOST', '192.168.1.11'); // 99% chance you won't need to change this value
You need to replace the 'name' with what ever your subdomain name is for weblogs.us, for example mine is mtekk.weblogs.us, your password should be what ever your origional wordpress administrator password was that either you requested from JD or what he sent you. Don't change the DB_HOST field since weblogs.us now has an seperate database server.
P.S. I did the same thing when I upgraded to 2.0 on December 31, and had to get it to work myself.
