Fatal error

I'm trying to learn Drupal and am still in the very early stages. I installed Drupal 7 on my website www.chasingbutterfliesdesign.com and added a little content. It showed up fine. I then decided to try my hand at theming and uploaded Zen and created my new theme "cbd" based on it. I started uploading a couple of modules and suddenly broke my site. I got the following error message:

Fatal error: require_once(): Failed opening required '/home/chasingb/public_html/sites/all/themes/zen/panels-layouts/zen-no-wrapper/zen_no_wrapper.inc' (include_path='.:/opt/alt/php55/usr/share/pear:/opt/alt/php55/usr/share/php') in /home/chasingb/public_html/sites/all/modules/ctools/includes/plugins.inc on line 477

I looked at the this file, /home/chasingb/public_html/sites/all/modules/ctools/includes/plugins.inc
but I don't quite understand what I'm supposed to add to it.

thanks for any hints you can send my way.
