Locked out of website

I recently installed Page Links To and set my home page to redirect to another site. The redirect works well except that I now can’t logon to my site using sa.dmcdirect.com.au/wp-admin so I now can’t remove the redirection or make any changes to my site. Is there another way in via a password or such like.

Your help would be appreciated,

The page I need help with: [log in to see the link]
