Loading db from an extended library

[eluser]Unknown[/eluser]
Hello,
I'm using CI 1.7.2 with PHP 5.
I'm trying to load data from a db to populate an array inside a library (language) I extended (ie: MY_language).
I tried doing the

Code:

$CI =& get_instance()

to be able to load db class but get an fatal error stating that:<br>

Code:

Call to undefined function get_instance() in /path/application/libraries/MY_Language.php on line [29]

The line #29 it's when it's trying reference the CI object.

Why do I want to do this? I need to be able to load the supported languages (supported by my app) to 3 different files, and want it to be automatic instead of hand-edited like now.

Any ideas?

Thanks,

Fefo
