MySqlDatabase Problem!

[GoldRapt]

John,
I don't know whose php package you have but you will remember these lines on installing?
$config['MasterServer']['username'] This variable contains the username provided to you by your host for connecting to your database server.
$config['MasterServer']['password'] The password that accompanies the database username should be entered here.
