Call to a member function validate() on a non-object using own library

I'm assuming this error means $CI is not an object. Like its not being defined like

Code:

$CI = New Generate_token();

If you loaded this like

Code:

$this->load->library('generate_token');

Then i think you might try to

Code:

$this->generate_token->validate($token);

//Please anybody correct me if i'm wrong. I'm also very new to CI but i'm trying to help as much as i can with my little knowledge of PHP

I am following everything like the manual
