The new version of the library was just released that allows you to set the sample rate, so if you set it to 44100, it should be able to read your WAV file.
Update: I just noticed that your screenshot states the "format" of the WAV file is "MPEG Audio" - it looks like your "converter" didn't really change the MP3 to a true wav file. So even if you set the sample rate to 44100, it might not work because the library might not be able to read that WAV file format correctly.
