I was given this keyboard as a birthday gift and the people who bought it for me got the display model. So, I downloaded the USB drive from Casio's website that says it works with this keyboard and I can't get it running at all. I'm planning on heading over to the store they bought it from and see if I can get the original CD-Rom, but if that doesn't work, I'd like to know how to get this damn thing to work on the USB cable. Thanks in advance.
