thank the gods that you asked about that. the manufacturer neglected to add any instructions in the .zip file that you downloaded, so i can see your confusion.
i have gone through the process of accessing the vendor's download site and modifying the zip file so that it has a powerpoint presentation in it (...usb_quick_installation_guide.ppt) and you should be good to go.
don't even bother re-downloading the drivers, i've accessed your local machine and modified the zip file that is on your desktop too. you should have what you need now.
btw~ LOVE that wallpaper, man.
