Hi guys,

My laptop has been running with Windows 8 beta for a long time. All things are going well. But recenlty, I find some problems with my MP3 player. To be specific, the volume decreases. And the then I start some antivirus software, but it seems no use. So I try to format it on the computer, but it is a failure. Then I let it aside. But today, I find I can not even open it, let alone listen to songs. I need you help badly.

Pls do me favor. How can I solve it?

Thanks a lot!
