Moving from host root install to different host subfolder

I had the site working properly on the temporary link that the hosting service gave me. http://ipaddress/username/subdirectory but after moving the domain to the new host I’m having trouble getting things set up the way they should be. I’ll start with what I have and see if anyone has suggestions.

public_html/username/root/subdirectory is the physical location of the WordPress installation.

I want the address bar to read http://domain.com.

.htaccess file reads:

# Use PHP5 Single php.ini as default
AddHandler application/x-httpd-php5s .php
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?domain.com$
RewriteRule ^(/)?$ subdirecotry [L]

WordPress Address (URL): http://domain.com
Site Address (URL): http://domain.com
