Modular Extensions - (HMVC) - Version 3.1.9

I have problem when call a model from a module controller.

This is my Module Controller :

Code:

class Adminmenu extends Module {
    function Adminmenu() {
        parent::Module();
        $this->load->module->model('menu','adminmenu');
    }
    
    function Index() {
        $this->load->module->view('menu_view');
    }
}

this is my model:

Code:

class Menu extends Model {
    var $id;
    var $parent_id;
    var $backname;
    var $main;
    var $viewable;
    var $addable;
    var $editable;
    var $deletable;
    
    function Menu() {
        parent::Model();
    }
    
    function getViewableModules($main=1,$parent=0) {
        $this->db->where('back',1);
        $this->db->where('viewable',1);
        $this->db->where('main',$main);
        $this->db->where('parent',$parent);
        $result = $this->db->get('modules');
        return $result;
    }
}

and this is my view:

Code:

class Menu extends Model {
    var $id;
    var $parent_id;
    var $backname;
    var $main;
    var $viewable;
    var $addable;
    var $editable;
    var $deletable;
    
    function Menu() {
        parent::Model();
    }
    
    function getViewableModules($main=1,$parent=0) {
        $this->db->where('back',1);
        $this->db->where('viewable',1);
        $this->db->where('main',$main);
        $this->db->where('parent',$parent);
        $result = $this->db->get('modules');
        return $result;
    }
}

and return error : "Fatal error: Class 'Model' not found in C:\Xampp\xampp\htdocs\ci161\system\admin\blocks\adminmenu\models\menu.php on line 2"

is there something wrong??

EDIT:
i call that module on my controller view
