Module not appearing in Admin tools

[dlcmpls 1]

I've installed the Discount Coupon Codes Contribution but the module is not appearing in Admin > Modules > Order Total.

 

I did see this in the Common Problems section of the README file:

 

# "Discount Coupon" does not appear in the list of Order Total modules under Modules > Order Total in the admin section.

Ensure that you have uploaded the module files contained in the contribution package:

catalog/includes/modules/order_total/ot_discount_coupon.php

catalog/includes/languages/english/modules/order_total/ot_discount_coupon.php

 

I've verified that each of the 2 files mentioned above are in the proper locations.

 

Here's what I see in Modules > Order Total right now:

 

Low Order Fee

Shipping 2 Info

Sub-Total 1 Info

Tax 3 Info

Total 4 Info

 

I've gone through the instructions twice, and verified that everything is correct, but I've obviously missed something.

 

Can anyone help?
