Thank you very much, BlackOrchid.

BlackOrchid,

I still can not hear it. It displayed following messages on my Windows Media Player:

Windows Media Player cannot play the file. The Player might not support the file type or might not support the code that was used to compress the file.

Sorry, I am really dumb when it comes to computer stuffs. I do not know how to fix it. Thank you anyway.

Have a wonderful weekend,

Rebecca
