Cron problem

[eluser]Ajaxian64[/eluser]
Hi all,
I've update my web app from CI 1.7.x to 2.0

Before this upgrade, my cron task worked fine but since Ci 2.0 then it doesn't work

Code:

// Emulate the http request
    $_SERVER['PATH_INFO'] = '/users/freeMe';
    $_SERVER['REQUEST_URI'] = '/users/freeMe';
    $_GET = '';

The result I have is that CI doesn't recognize the url and the Router class said "No URI present. Default Controller Set"

Is there something changed in CI 2.0 regarding this ?
