Getting error message when trying to access newly created subdomain dashboard

I’ve scoured the forums and I can’t seem to find a resolution to my particular problem. I’ve followed the directions to setting up Multisite carefully. I’ve added the wildcard subdomain at my host (Bluehost – which subsequently never shows underneath my added subdomains. Not sure if that means anything.)
I’m to a point now where I can add a site, but it never shows under my dropdown (only under “Sites”) and I get this message when trying to access it: “The webpage is not available”

From my reading, I keep seeing that if you get that sort of error message that your .htaccess file may be incorrect. This is what I have in there (which is exactly what the Network Setup spit out):

<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>

Hoping someone can point me in the right direction. I’m not a WordPress pro, but I’m capable of following directions and have been running two WordPress sites successfully for 3 years. With that being said, please feel free to explain things to me as if I were 4-years-old. lol

My domain is http://www.wegotkidz.com, and the subdomain I’m trying to create is curlz.wegotkidz.com.

Thanks in advance!
