Error when load cache driver

[eluser]Halan Batista[/eluser]
Hello!

I'm having problem trying to load the driver cache.

I'm using:

Code:

$this->load->driver('cache');

And is giving the following error:

Code:

Fatal error: Call to undefined method CI_Loader::driver() in /Applications/XAMPP/xamppfiles/htdocs/www/iuser/system/application/app-iuser/models/perfil_model.php on line 854

How I resolve it??

Drivers require CodeIgniter 2.0+.

[eluser]Halan Batista[/eluser]
My version is 1.7

How can I use?

Just upgrade incrementally.
