So that'll be /yourstore/extra_configures/checkout.php

The instructions say this exactly.

Fast and Easy Checkout for Zen Cart is activated by loading an extra_configures file called checkout.php before the filenames.php file.

This causes definitions for the checkout links to be defined to direct customers to the new integrated checkout page. To deactivate the script without running the uninstall.sql and deleting all of the files, simply rename or delete the file includes/extra_configures/checkout.php.
It is strange that people have not realized Easy Sign-Up and Login is an upgraded version of Checkout Without an Account. It has more features and completely integrates with FEC.

For any shipping problems, I suggest using the new version which was released yesterday. If you do not yet see it on the Zen Cart website, you can always download it from Numinix. Since we control our own server, updates are made available instantly. We also have a weekly newsletter to keep visitors informed of updates, bug fixes, patches, and developments currently underway.
