Hello,
Book Library Pro and free version work very very like
so where from that error - difficult say.
May be you install some thing also ?
Please try in file:
{yours site}/administrator/components/com_booklibrary/functions.php
find row:
require_once (JPATH_ROOT .DS.'libraries'.DS.'joomla'.DS.'database'.DS.'table'.DS.'menu.php' );
and replace to:
JLoader::register('JTableMenu', JPATH_LIBRARIES.DS.'joomla'.DS.'database'.DS.'table'.DS.'menu.php'
