Running CodeIgniter from Subfolder on Godaddy

Nope...

I'm testing locally on my Mac (10.6), PHP 5.3.3. The site is hosted at GoDaddy on a Linux box with PHP 5.2.17.

Locally I can change the require statement of the CodeIgnitor core (in the bottom of index.php) from:
require_once BASEPATH.'core/CodeIgniter'.EXT;
to
require_once BASEPATH.'core/codeigniter'.EXT;
and everything works fine.

Changing this on GoDaddy's environment kills the app with a PHP warning (failed to open stream).

Maybe I should contact GoDaddy??
