Domain issues

I have found that rather than follow most tutorials and only have to enter:

http://www.stat30fbliss.com/wp-admin/install.php

I had to enter stat30fbliss.com/wordpress/wp-admin/install.php

I have gone through the install, although I have not published my first post, but now my domain, stat30fbliss.com shows me an error, the same error as stat30fbliss.com/wordpress.

I am assuming this is a newbie FTP mess up. Any help is appreciated.
