HMVC not working trying to show view partial in CI 3.1.4

Hello, I started using HMVC today (https://bitbucket.org/wiredesignz/codeig...sions-hmvc) and I've got to put the code to work as a module modifying MX_Loader (there was a missing function so I read), but when I tried to show the module as a view partial I get this error "Fatal error: Cannot redeclare class CI in C:\Datos\www\gastronegocios\application\third_party\MX\Base.php on line 57". This is my code:

Module Controller

PHP Code:

class Ivanblue extends MX_Controller {
   function __construct()
   {
      parent::__construct();
      date_default_timezone_set("America/Asuncion");

      $this->load->helper("url");
   }

   public function index()
   {
      $this->load->view("ivanblue");
   }
} 


Module View

Code:

When I go to the controller directly at "http://localhost/gastronegocios/ivanblue" it works perfectly, but when I try to use it as a view partial I get the error "Fatal error: Cannot redeclare class CI in C:\Datos\www\gastronegocios\application\third_party\MX\Base.php on line 57".

This is how I'm trying to show it as a view partial, inside a normal view:

Code:

html code...
<?php echo modules::run("ivanblue"); ?>
html code...

How can I get this working? Thanks in advance.
