Affiliates Marketpress Addon??

I bought membership explicitly so I could use the Marketpress and Affiliates plugins together, as the plugins page mentions multiple times that they integrate beautifully together.

I have my Marketpress store set up, however I see no integration at all. Upon setting up the Affiliates plugin it is clear it is configured for paid memberships, not products. So I activated the Marketpress add on under the Affiliates tab... and nothing. It is still set up the same way; I can't see where it made ANY changes at all.

Please help me! Have I done something wrong? Missed something?
