Corsair raptor m45 mouse not working PLEASE HELP

A couple of hours ago I bought a Corsair m45 gaming mouse.. as soon as I went home.. I plugged it in on my usb 2.0 port.. I was surprise , because it's mouse cursor doesn't response at all.. and then I thought, maybe the reason behind because I haven't install it's driver and firmware yet.. so I installed and run the said two programs... but then.. nothing happened . I tried rebooting my pc a couple of times, re-installing it's driver and firmware, switching the mouse to all of my usb ports.. and nothing happen!.. still unresponsive.. however.. windows detected the said device, corsair software also detected the mouse.. but the mouse itself is not responding to all button clicks and drag..

PLEASE HELP IM SO DESPERATE! :(
