Own Shipping Module for Magento - Next step in onepage checkout does not work anymore.

Question

Cheers, I created my own shipping module for magento 1.4.1.1. , which so far does not work. After really getting frustrated with this, I exactly copied everything from http://www.magentocommerce.com/wiki/5_-_modules_and_development/shipping/create-shipping-method-module .

As with my own module, it does not work. In the onepage checkout, I cannot go further when entering the shipping adress, and firebug indicates, that my shipping method does not appear in the list of available shipping options.

My model class indeed is loaded, I solved this problem earlier. But for some strange reason it will not appear in the frontend and again, I am currently using the exact files from the wiki.

Please, does anybody have any ideas what could be going wrong here?

Thanks in advance!

Edit: this is my config xml:
