Sometimes...when I edit a music file or convert the format...a given player/program may refer it as "headerless PCM data" and I interpret this as a way of saying "I cannot read this file."
What I do then is use another program to change the tag and filename...and it can be read.
In your case, you might take a look at those two things...and see if you can shorten the filename via a simple change. Some music that is downloaded via the Internet comes with rather long names and that may be problem.
This happened again today...and I was incorrect about the filename/tags. The problem is the file format and it seems to be a quirky one. Even though some files are encoded as .mp3 and will play in certain/all players...when I use Cool Edit 2K, it can't read some of them. So I simply use Real Player to "convert" the files to my custom mp3 format (192) and CE2K can now read/play/edit said files.
