Troubles integrating PGP into SPC

I have a couple questions, but I'll start with this one first.

This is the first time we have installed SPC in our environment. I am going through steps to integrate our other products, but I'm having trouble with PGP. I have already integrated Endpoint and Messaging Gateway with only minor issues. (One being that the Endpoint integration shows a Connection Error with time being the problem.)

In trying to integrate PGP with Protection Center, it was able to find the correct product with the Discovery feature. But when I try to enable PGP I am getting an error. Here is what it looks like.

The account being used to enable PGP is the superuser acount on the PGP Server.

Thank you in advance for any help.
