From the readme file in the mod zip:

Reward Point Mod Diagnostic Tool.

This is available here: http://www.omnicia.com/rpd.zip

If you have renamed your admin folder, you will need to open up rpd.xml in a plain text editor and change admin to your actual admin folder name

PHP Code:
<?xml version="1.0" encoding="windows-1252"?>
<rpa>
    <folders>
        <folder>admin
If memory is correct LOL you upload the files to your store directory then browse to your_site/your_store/rpd.php and it will give you a list of all files and if they are still there or missing :)
