Throw it into Audacity (completely free) & then export it as 'WAV (Microsoft) signed 16-bit PCM' & then try it again.

Audacity Export:
'File' tab > 'Export' > 'Export Audio...' (Ctrl+Shft+E) > 'Save as type' dropdown = 'WAV (Microsoft) signed 16-bit PCM' > 'Save'

Make sure the file is mono as well
