I need help with a settings option

I’m following a video tutorials in which the person appears to be using version 3.0.4 whiles I am using version 3.1.
We installed an adsense optimizer plugin and after going to settings,he had sub-options(under the settings) with Adsense Optimizer being the last of those options, and General Settings as his “main page title” whiles I have NO sub-options(under the settings) for me to choose the “Adsense Optimizer”. I really need this option “Adsense Optimizer” which I’ve already installed to change some settings now!!!
PLEASE HELP ME…
