Two finger scrolling not working on touchpad

So I bought a new Alienware 13 not two days ago. Windows 8.1. I was on Twitch when suddenly the touch pad's scrolling capabilities stopped working. All online tutorials tell me to access to access the control panel through the start screen. The tutorial tells me to move my mouse to the lower right side of the screen in choose "settings." Next I'm supposed to chose "control panel" but that option doesn't exist. I have a button to access the control panel in the "PC settings" page but it doesn't do anything. Does anyone know what the problem is?
