Error establishing a database connection using MS WebMatrix

I’m a newbie to WordPress websites. Built a wordpress website running the Chameleon Theme from Elegant Themes. Used the Microsoft WebMatrix to access and build my website on my computer.

Decided yesterday to take the site live for testing. Followed some instructions from Network Solutions (my host) on how to FTP my WordPress files and while I was able to install WordPress onto my server, I can no longer open the website on my local directory (through WebMatrix) to export the files. So now I cannot access the website anywhere!

I can see all the files for my site on my computer. As far as I can tell, my wp-config file is fine, including the username, password, host, etc.:

/** The name of the database for WordPress */
define(‘DB_NAME’, ‘database_name_here’);

/** MySQL database username */
define(‘DB_USER’, ‘username_here’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘password_here’);

/** MySQL hostname */
define(‘DB_HOST’, ‘localhost’);

/** Database Charset to use in creating database tables. */
define(‘DB_CHARSET’, ‘utf8’);

/** The Database Collate type. Don’t change this if in doubt. */
define(‘DB_COLLATE’, ”);

Can anyone help me? Is there a workaround? Any help would be greatly appreciated! This is making me crazy!
