Copying drupal 6.24 live website to desktop computer

Hello everyone:
I am completely new to Drupal, so please bear with me.

I created a Drupal 6.24 test site (using XAMPP 1.8) on my computer (windows 7 ultra) and copied a live Drupal 6.24 (including the database) to this test site. The structure is a multi site format.

Sites folder in drupal 6.24 (htdocs/drupal-6.24) contains the following folders: all, greetingcards, default

The windows host file contains the following: 127.0.0.1 greetingcards

The file httpd-vhosts.conf contains the following:
##ServerAdmin postmaster@dummy-host2.localhost
DocumentRoot "C:/xampp/htdocs/drupal-6.24"
ServerName greetingcards
##ServerAlias www.dummy-host2.localhost
##ErrorLog "logs/dummy-host2.localhost-error.log"
##CustomLog "logs/dummy-host2.localhost-access.log" combined

The problem occurs when I enter the path to my greetingcards site: http://greetingcards

Instead of being able to view the copy of the live site, I end up viewing the admin page. The page containing the header: "Welcome to your new Drupal website!".
I've done this numerous times. Always the same result.

The settings.php file contains the following:

$db_url = 'mysqli://root:password@localhost/greetingcards';

$db_prefix = 'drupal_';

$update_free_access = FALSE;

$base_url = 'http://greetingcards'; // NO trailing slash!

ini_set('arg_separator.output', '&');
ini_set('magic_quotes_runtime', 0);
ini_set('magic_quotes_sybase', 0);
ini_set('session.cache_expire', 200000);
ini_set('session.cache_limiter', 'none');
ini_set('session.cookie_lifetime', 2000000);
ini_set('session.gc_maxlifetime', 200000);
ini_set('session.save_handler', 'user');
ini_set('session.use_cookies', 1);
ini_set('session.use_only_cookies', 1);
ini_set('session.use_trans_sid', 0);
ini_set('url_rewriter.tags', '');

Thank you for any help you can offer me.
