Problemen met aangekocht template

Hallo,

Ik krijg deze vermelding wanneer ik deze pas aangekocht template probeer te activeren:

Warning: require_once(/home/content/67/8302367/html/wp-content/themes/theme1178/includes/register-widgets.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/67/8302367/html/wp-content/themes/theme1178/functions.php on line 57

Fatal error: require_once() [function.require]: Failed opening required ‘/home/content/67/8302367/html/wp-content/themes/theme1178/includes/register-widgets.php’ (include_path=’.:/usr/local/php5/lib/php’) in /home/content/67/8302367/html/wp-content/themes/theme1178/functions.php on line 57

Kan er iemand mij laten weten wat hier juist fout gaat en hoe ik dit kan oplossen ?

Bedankt.
