Shadowbox cannot find any of its support files - language, players, etc.
You are loading shadowbox.css and shadowbox.js from a folder called shadowbox. Shadowbox also expects all its support files to be within that same folder, in sub-folders like players/ (for all the player files), languages/ (for the language files), adapters/ (for adapter files), and libraries/ (for Sizzle, mediaplayer, swfobject, etc). None of these appear to be on your system.
