Error updating Domain Mapping Plugin - Sunrise ON

Hi Guys, I Try to update domain mapping plugin but it didin't work. When I try to access a map domain: http://www.mindtv.com.br it get backs to home or register page.
When I try to access Settings - Domain Mapping I get this:
´Please edit your /home1/marcelo/public_html/wp-config.php and move the line define( 'SUNRISE', 'on' ); above the last require_once() in that file or make sure you updated sunrise.php.´

I already try to edit wp-config.php or use the old sunrise.php, but nothing changes. Any ideas?
thanks.
