mp3 files not playing on Windows

[FORD JR., CURT]

A client's customer (using Windows) had ordered two modules of a series. Both come with their own set of mp3 files in a folder named "media."  The two modules use the same code for figuring path names and playing sounds. We've had no problems in either module with other customers, but this one reports that sounds play properly in one of the modules, but not the other.

He has QuickTime installed, and we've ruled out non-standard characters in the path to the sound files. What seems strange is that the sounds play in one module, but not another. I suggested he move the problematic module to the same location as the one that works as expected, but it doesn't seem to have helped.

Anybody have any ideas of what else to check?

Thanks!
