回複：能不能說詳細（準確）一點，好給你參謀參謀。盡管不用MAC

thank you for you response!

Problem one, when I click the posted music, my computer tells me "can not open the file, verify that the path and file name , and try again"
Problem two, Sometimes, even though the files can be opened, there is no play.

thanks again, and I am on line now
