Gallery Images Grid Error

Uploaded and installed, but when activated I get an error across the top of my site:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘lc_video_embed_module_i18n’ not found or invalid function name in /home/quarrysc/public_html/test/wp-includes/plugin.php on line 503

Any suggestions?
