Fatal Error When WpAdmin page

Hi!

I can’t access the site and the admin page anymore. This is the message that appears everytime I open the site;

“Warning: require_once(__DIR__/composer/autoload_real.php) [function.require-once]: failed to open stream: No such file or directory in /home/kantmarble/domains/kantmarble.com/public_html/wp-content/themes/u-design/inc/admin/u-design-merlin/vendor/autoload.php on line 5

Fatal error: require_once() [function.require]: Failed opening required ‘__DIR__/composer/autoload_real.php’ (include_path=’.:/usr/local/lsws/lsphp5/lib/php’) in /home/kantmarble/domains/kantmarble.com/public_html/wp-content/themes/u-design/inc/admin/u-design-merlin/vendor/autoload.php on line 5”

How to fix this? Any help?
