No dashboard or style sheet for the 2nd site of a new Multisite install.

Hi,

I followed the manual for a sub-directory install of Multisite.

The main page works fine.

However, after creating a 2nd site, I cannot access its dashboard.
Also, when I visit the site, there is no style sheet assigned to the site.

Here are the links:
http://register4tkd.com/
http://register4tkd.com/atlantachallenge/

Here is my htaccess:

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

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) home/content/27/8748627/html/register4tkd2013/$2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ home/content/27/8748627/html/register4tkd2013/$2 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

Here is a slice of the wp-config:

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'register4tkd.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

Thanks,

David
