Hey! I'm so happy that i finally get my CLP-635! But i can't connect it via USB to PC :( I don't know - is it my PC not detecting piano? or maybe piano doesn't detect PC? I've searched all the forums and I can't find any anwsers. I did everything like it's shown in Owner's Manual and still nothing. USB cable is working - I'm using it everyday. It makes so depressed. Any ideas?
