You can either go back to the old setup, or try to make this work.
To revert, FTP into your domain and rename mobiletechaddicts.com to mobiletechaddicts.new and mobiletechaddicts.com.old to mobiletechaddicts.com
Then go to the panel under Goodies -> Manage MySQL and Restore your database to a previous date. Pick the option to keep the table names and rename the old ones to something like tablename_date
To fix the one you have, FTP to your site and make sure that the new wp-config.php file looks somewhat like the one in the .old directory. If you have special plugins or themes you added to the old site's wp-content directory, copy them from the .old setup to the current one.
