How to convert .umx files to .mp3, .wav, .wma etc?

I just bought a CD a few days ago, and it came with this special software (U-MYX) where you can make a remix of the song. unfortuantely, you can only save the finished remix as a .umx file. Is there any way i can convert this to .mp3, .wav, .wma, .ogg, or any other media format???
