MimiLee,

Right click on one of those files in your songlist.

Then click PROPERTIES, then click SUMMARY.

If it is a normal WAV track the specs should read somewhere as follows:

Bit rate..................... 1411kbps
Audio sample size........ 16bit
Channels................... Stereo or Monaural
Audio sample rate........ 44KHz
Audio, format............. PCM

I believe the two most critical ones would be the audio sample size and especially the audio sample rate.

If anything but the above, then the files are not standard WAV files and most likely won't work unless you have an audio editing program such as Goldwave, and can re-sample the tracks.

Let us know what you find.
