Hello, I need help.

Hello, I have a casio wk-210 , i did recorded a song inside the keyboard , now I am trying to download the recorded song into audacity software. I downloaded the casio data manager 5.0 and also NCH software inside the keyboard. I connected the keyboard to the computer via usb A to USB B . On the casio data management 5.0. I choose Recorded Song , then on the right side of the screen I see the SG1 size is 19756 , but the other SG2 through SG5 are empty. Also I don't see anything else. I only can hear the beeping sound when I plug or unplug the keyboard from the computer. That is all what I can see. Please help me if you have any advice and knowdledge. Thanks. I
