致命错误：在sQcrm中找不到类'BaseObject'

I'm trying to install http://sqcrm.com and when I finish with the Setup steps I receive this error.

Fatal error: Class 'BaseObject' not found in /home/public_html/class/core/radria/DataObject.class.php on line 9

And this is the code the php file have:

<?php
class DataObject extends BaseObject {
//-- values array to hold key value data
protected $values = Array();
//-- holds the key for values array
public $fields;
//-- holds the db conn object from Doctrine
public $dbcon ;
//-- holds the table name
public $table ;
//-- holds the primary_key of a table
protected $primary_key = '';
//-- holds the result set of a query
public $result ;
//-- holds the string sql query
public $sql_query = '';

` Thanks in advance.
