WPMU Affiliate Plugin with Market Press add-on

I've installed and installed WPMU Affiliate Plugin with Market Press add-on. Both are updated to the latest versions.

Your usage instruction says "you’ll see a new Affiliate Settings section in the MarketPress settings at Products > Store Settings > Payments."

But there is no longer "Products > Store Settings > Payments" since your last update of the Marketpress plugin.

There are only:

1) Store Settings -> Payments

and

2) Store -> Products.

I am not seeing any Affiliate Settings section in the MarketPress settings at in either of the above mentioned location.

How do I then "Enter a value for the Set percentage to be paid to affiliates option to credit affiliates a percentage of the referrals they make resulting in MarketPress product sales."?

Please help. Thanks!
