Considering when the last update was for s2M, in the meantime, some documentation is becoming outdated. One element that is to re-write is the documentation on Paypal. In fact, Paypal has changed things around so in order to help users set up their Paypal correctly, they are currently a bit lost as the API and other elements are no longer found where s2M directs them.
This is just a mention for the next update when it happens.
