Thank you so much for your response. I did not intend any insult and I do appreciate the work that goes into the mod and more specifically, answering all these questions.

That said, on this add on download page, http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=310, are you refering to this version:
This is a maintenance release that incorporating changes made for Zen Cart 1.3.8. There are no functional enhancements.
Author: Kuroi
Version: 4.7
Zen Cart™ Version: v1.3.8
Update added on Dec 02 2007

Can you tell me if it works with 1.3.8a with security patches? If so, would you be able to tell me what would be involved in reverting back to this version? would I need to make changes to the db or just over right files?

Thank for your time.
