The one I installed was called WavePad and was freeware. Don't remember where I got it but you can do an Internet search to find it.
Basically the problem is the location of the files you are trying to play. Vista will not allow using any files that are editable from the C:\Program Files area and the older Microstudio stored those files in that location. You can copy/move them to another area and they should work.
