回复：能不能说详细（准确）一点，好给你参谋参谋。尽管不用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
