NAudio WMA to WAV Conversion Error

Hello, I am trying to convert a .wma byte array to a .wav stream ( I am using the NAudio plug-in ) , for the purpose of creating an AudioClip, here is the code I use ( pretty sure it's wrong but the best I can do ) :

     public static AudioClip FromWMAData(byte[] data)
     {
         System.IO.File.WriteAllBytes("wmatemp.wma", data);
         WMAFileReader wmareader = new WMAFileReader("wmatemp.wma");
         WaveStream waveStream = WaveFormatConversionStream.CreatePcmStream(wmareader);
         WAV wav = new WAV(AudioMemStream(waveStream).ToArray());
         AudioClip audioClip = AudioClip.Create("wma", wav.SampleCount, wav.ChannelCount, wav.Frequency, false);
         if (wav.ChannelCount == 2)
         {
             float[] sampleData = RemixChannels(wav.LeftChannel, wav.RightChannel);
             audioClip.SetData(sampleData, 0);
         }
         else
         {
             audioClip.SetData(wav.LeftChannel, 0);
         }
         // Return the clip
         return audioClip;
     }

However, the program exits, and I am not able to catch an exception of the error, studying the crash dumps I found out that the exception was: "The thread tried to read from or write to a virtual address for which it does not have the appropriate access." Can someone please enlighten me as to what this means ? Or offer a different alternative to converting .wma to .wav, thank you !
