I was converting some mp3 files to WAV IMA ADPCM format and It did it very fine and fast... But later, I attempted to play them with Windows Media and it didn't play it! They have 0 bytes of size, no sound! Even in Audacity I opened one of the same converted files and I found that it has no sound.

I don't know what is comming on! I'm using the trial version of Music Converter and I'm not sure if I need some codecs (which I'm not a good in this topic) Please, I need the help of experienced and patients users.

Greetings, I hope your answers
