HMVC $this->load->view doesn't work after Modules:run

[eluser]Unknown[/eluser]
After calling Modules::run, I get always this error:
An Error Was Encountered
Unable to load the requested file: index.php

My modules folder structure:

modules
-admin
----models
----controllers
--------admin.php
----views
--------index.php
-login
----model
--------login_model.php
----controllers
--------login.php
----views
--------login_form.php

...some code...

in Admin::__construct()

Code:

parent::__construct();
Modules::run("login/is_logged_in");

In Login::is_logged_in(), check if isset session userdata for logged user, if not i redirect to login/index

In Login::index i validate input form login form, show login form(loading view), set session userdata and redirect to admin/index

in Admin::index()

Code:

$this->load->view("index");

All the login system works good as the redirect from admin to login in case of not logged in user, so the only problem is to load view after Modules::run().

Thanks in advance for replies.
