404 Error at wp-admin page

I just auto installed wordpress on bluehost. I not get a 404 on the admin part of my page (fineartschorale.org). I previously had the site hosted through yahoo and I’ve taken over the site. Bluehost has better WordPress integration, but now that I bought the Bluehost hosting package, I still can’t access the site.

I have no idea why this is happening or how to even begin to fix it. Any insight would be appreciated. I can provide other relevant info if you need.
