Localhost — keep getting 404 error

Trying to set up MAMP and use wordpress on my computer. All goes well until I try to connect with the localhost. I keep getting a 404 error.

Tried using the http://localhost:8888/wordpress/wp-login.php and various configurations to no avail

Here are my current settings:
OS X (10.7.5)
MAMP:
Apache port is 8888
MySQL port is 8889
PHP 5.3.5
Document root: /Applications/MAMP/htdocs/wordpress
Database: wordpress

I’ve tried entering the above address after changing the wp-config-sample.php and saving to the same folder as wp-config.php:
/** The name of the database for WordPress */
define(‘DB_NAME’, ‘wordpress’);
/** MySQL database username */
define(‘DB_USER’, ‘root’);
/** MySQL database password */
define(‘DB_PASSWORD’, ‘root’);
/** MySQL hostname */
define(‘DB_HOST’, ‘localhost:8889’);
