Audience Management API: RSA Key Container Does Not Open

This is the next question to this: Outbound Email Profile API: Get a List of Email Addresses

I am writing a simple example to learn the audience management API. All the code I have here.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Tridion.AudienceManagement.API;

namespace OEPasswordEncrypt
{
    class Program
    {
        static void Main(string[] args)
        {
            StaticAddressBook importAddressBook = new StaticAddressBook(new UserContext());
        }
    }
}

The error I get when starting on the CM server is this:

Unhandled Exception: System.TypeInitializationException: The type initializer for 'Tridion.AudienceManagement.DomainModel.Utilities.Configuration' threw an exception. ---> Tridion.AudienceManagement.DomainModel.Exceptions.LocalizableConfiguationErrorsException: Loading of the configuration failed. ---> System.Configuration.ConfigurationErrorsException: The RSA key container could not be opened.

I already tried to run aspnet_regiis TridionRsaKeyContainer with my own username, but this suggests that the RSA key container does not exist.
