Trouble Installing

Hello, for a few days now I’ve been trying to install WordPress.
My URL is HouseOfKouture.com, I’m Hosting with Godaddy, and My Domain is From them as well. I’ve Tried Using The one-click install, Manual Install, I’ve checked and The Name servers are correct. Whenever I try Running the WordPress installation script, I get a 404 error page (from wordpress.COM) saying the Page Doesn’t exist(it redirects to:http://houseofkouturesp.wordpress.com/wp-admin/activate):[ I have it in the root directory, and I’ve also checked my Config file, and everything is correct. Can someone Please Help!:]
