After I uploaded the QuickBooks Sync files nothing shows up in my Zen Cart Admin under Admin->Configuration->Quickbooks Sync

Has anyone else encountered this problem?

Your help would be greatly appreciated.

Here is the setup.

I am running Zen Cart 1.5.1.

The Zen Cart Quick Book Sync Web Service 2.pdf says to upload these files
/admin/qbAdmin.php
/admin/qbMatch.php
admin/includes/boxes/extra_boxes/qbSync.php
/quickbooksSync/qbClass.php
/qbServer.php

The zip file also contains /admin/qbBuildQue.php which I also uploaded to my admin folder.

Here's where I uploaded them:
mystore/admin/qbAdmin.php
mystore/admin/qbMatch.php
mystore/admin/qbBuildQue.php
mystore/admin/includes/boxes/extra_boxes/qbSync.php
mystore/quickbooksSync/qbClass.php
mystore/qbServer.php

I even tried putting the qbClass.php and qbServer.php files in my admin folder root.

Thank you for reading this, and hopefully your solution.
