Please look in the wp-admin folder for two files, .htaccess and .htpasswd. These are hidden files so your FTP client of file manager needs to be set to display hidden files. If they are there, delete them both. We're talking about wp-admin, NOT the root of your site.
These two files are added by the Admin Tools first run wizard to protect your administrator files. Deleting them disables that protection. You can enable it from the Admin Tools Control Panel.
