Site redirect accident. Unable to access site via "wp-admin.php" anymore.

I just purchased a new domain which I was attempting to redirect my WordPress site (imagesdubois.com) to. In the admin settings I changed the URL option from imagesdubois.com to my new domain. However, I didn’t set up the re-direct appropriately, so the new domain is inactive.

Therefore, I am unable to log in to my www.ads-software.com site at all to change the settings back to the old URL. I tried restoring my site/files to a previous date and this didn’t work.

All I need to do is go in to my settings and change back the URL, I’ve tried logging in to my admin page from the www.ads-software.com homepage and was unable to gain access as well.

Thanks for the help!
