Problem with MatchBox and autoloading the session class

[eluser]Unknown[/eluser]
When i try to autoload session class from a module in MatchBox i retrieve this error:

Code:

An Error Was Encountered

Matchbox: Unable to load the requested class: session

Here is the autoload.php

Code:

$autoload['libraries'] = array('database','session','Pledgie');

This file i in modules/matchbox/config

It´s loads perfectly the 'database' class but not 'session' class. I have the same error with form_validation.

Any suggestion?

Thanks!!1

I am also receiving an error when trying to pre-load the session class.
