Class 'CI_Controller' not found after upgrading CI 2.0.x -> latest - in MY_Router.php

[eluser]Out of Control[/eluser]
I actually had &DB;();

Not sure where the extra semicolon came from in my post. Regardless, removing & made no difference. Same error as the router gets run before CI_Controller is loaded in CodeIgniter.php. The only idea I can come up with is that I had hacked the core before I upgraded.

Note to self: Less Guiness and more sleep
