Redirect can't login or visit my site

My site is hosted by wordpress…
I logged in and changed the web address which was originally http://swaggcentral.com towww.swaggcentral.com

I did not no that doing this would cause my site to disappear. when you try to go to it… my site says “THIS WEBPAGE HAS A REDIRECT LOOP”

Now every time I try to login wordpress. It rejects me from doing so…
I can’t login nor can any of the other admins…

If I can’t login in I can’t change the address back to normal.

I don’t know what to do please help.

Thanks,
