The Dreaded 404

I just setup my WP site at fathersupliftingfathers.org, well I changed the site to appear at fathersupliftingfathers.org, not fathersupliftingfathers.org/fathersupliftfathers, and now the site goes straight to a 404 message. Once I go back to the old login page, it comes up in a barebones fashion, and I log and then another 404 comes up.

Any help would be greatly appreciated.
