How do I access S2 Member Pro functionality?

I know this is probably a really dumb question, but we’ve just purchased S2 Member Pro. I’ve installed it and it says it’s active. I’m trying to access the payment gateway options which reading the documentations says are accessed through:
Dashboard > S2 Member (Pro) > Other Gateways

But I seem to only be able to access the General Options page from the settings option under S2 Member Framework. My user account as Administrator level security. I’m guessing I should get the settings option next to the S2 Member Pro add in.

Can anyone help?

I found the issue. It was because whilst I had admin rights I also had some other user rights in that profile and the other user rights were causing some of the functionality to get turned off. Now I just have admin rights I can see everything.
