Just purchased a year subscription, not smart enough to install- it claims all I have to do is plug

I'm running 3.7.1 Wordpress multisite, w/WooCommerce and S2Member networked but not configured. I accepted your claim as to how easy it would be and with all the plug-ins available I bought a year subscription. Have no cue from your instructions on how to convert or install. You dashboard appears sat the top, but not when I revert to wordpress. If you don't want me to undo my subscription, I suggest someone walk me through this
