My admin login-in goes to the .COM homepage

Hello, all:

I got an email yesterday after moving me .com blog to .org giving me a new admin log-in: deborahrutter.com/wp-admin.

I got in there once, used the export/import tool to move my old info over to my new blog, but I monkeyed with, I think, with the domain names because NOW when I type in the above, I go to http://www.wordpress.com. And I am no genius, but I know that’s not right.

Since I know can’t reach my blog at all, is there someone who can go into my site and fix/reset? Is there magic I can do?

I am hoping this will solve it so I can be on my way!
