Menu item container module

I downloaded the developmental 7.1 version of this module (menu_item_container_-7.x-1.x dev. tar.gz) and now receive the following errors:

•Notice: Undefined index: menu_item_link in menu_item_container_theme_registry_alter() (line 64 of /home/content/54/8435954/html/sites/all/modules/menu_item_container/menu_item_container.module).

I am new to Drupal and know little about php program language; so please, bear with me if I do not immediately understand what you are trying to say. Any help is greatly appreciated. Thanks!
