Adventurous-free: Fatal Error

First, let me say what beautiful, wonderful work you are producing. Top quality themes. I installed Adventurous Free version, all was well. Now, however, and I don't know why, I am getting a Fatal Error on every page I go to. The Error is: Fatal error: Call to undefined function wp_script_add_data() in /home/kcb8d4al/public_html/wp-content/themes/adventurous/inc/adventurous-functions.php on line 77 I tried to do a Dropbox restore but that has failed so I am stuck. Looking forward to your response. My web site is http://pete-smith-online.com thank you.
