I'm trying to setup "Paypal Payments Pro"

So I have to set up "Express" with this. In Express it tells me to enter in:

API Signature -- Username
API Signature -- Password
API Signature -- Signature Code

I know my "username and password" from "Profile > API Access > Request API Credentials

I can't find the "56-character code" anywhere.

Does anyone know where I can find it?

so right now my Payment Module is stating:
"PayPal Express Checkout NOT CONFIGURED YET"
"PayPal Website Payments Pro NOT CONFIGURED YET"

I use "Godaddy" and on "Zen-Cart 1.3.8a"
