I've been through this thread and didn't see the answer to my solution; however, I may have missed it.

I've installed this mod without any complication. When I assign points to a user through the admin interface, they appear within the account edit page but they don't have any value tied to them.

Total Reward Points: 1001
Total Reward Point Value:

Also, during the checkout process, the call out to redeem to reward points doesn't appear.

The points show up with the products. When they are purchased the points are added to the users account... the mod is mostly functional.

I ran the rpd.php testing file and all of the files, directories, and tables are in place.

I'm using Version 1.29a of the mod and 1.3.8 of Zen Cart

Any ideas?
