Rewrote htaccess and wp-config for multisite and it's not working

Hi, I’m working on setting up a multisite network for a client. This is my first attempt at making a network through WordPress so bear with me. I followed all the steps here: http://codex.wordpress.org/Create_A_Network and once I got to step 5 I got stopped.

I rewrote the htaccess file and wp-config file just like it told me in the Network Setup menu, uploaded them, then re-logged in. I’m not seeing the “My Sites” option in the admin bar. When I go to Tools > Network Setup, it gives me this error:

Warning: An existing WordPress network was detected.
Please complete the configuration steps. To create a new network, you will need to empty or remove the network database tables.

and also prompts me to rewrite the htaccess and wp-config file again.

Here’s the htaccess WordPress code:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</IfModule>

and here’s the wp-config code:

* Multisite */
define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'justaskva.org');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
/* That's all, stop editing! Happy blogging. */

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
	define('ABSPATH', dirname(__FILE__) . '/');

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
