theme upgrade problem

Yesterday I tried to post a problem in this forum but it is still not displaying here. When I upgraded Adventurous Pro from v3.8.1 to v3.9 the site crashed. It seems a line in the child theme's functions.php (which I downloaded from your site) is trying to find a file named '/inc/panel/adventurous-theme-options.php'. This file does not seem to exist in the 3.9 version of the parent theme. How can I fix this problem so my child theme will work with the 3.9 version of the theme?
