Sometimes the place we get the music from has problems. But if it worked on lyoru other computer, that apparently isn't the problem.
A lot of us have discovered we really like AVAST (free) antivirus. That and 'Malwarebytes anti-malware' seem to keep things in good shape. SO if you think it might be that kind of problem..it woudlnt hurt to try those. (just remember you can only run one antivirus program at a time, so if you want to download Avast, you have to uninstall the one you're currently using).
One more thing. I found that if I have an embedded music player on my page...I lose my 'comment toolbar'...& people have to go to my Guestbook in order to leave comments; so I dumped the embedded player. I've gone back to using just the NOTH music player. But it's up to you. A lot of people use embedded layers with no real problems. Some have the problem I did--& just don't worry about it.
Good luck...maybe someone else will have other ideas for you.
