Hello everyone, seems I get a problem. My computer suddenly cannot detect my HD400 since yesterday. It works fine before. I have installed the driver, but the Monkey keeps showing that I haven't. And when I connect it to computer, there is no sound (I mean the system sound of Windows for a USB plug in). The cable should work fine, I test it with another device. Is there a hardware problem or simply because the driver cannot be installed properly?
