Downloaded, but doesn't work.

Opening a .wav file seems to work just fine.
Under "Select Input File Type" a .cdg file is an option. Since I'm working with karaoke files I assumed that I could open this type of file. Wrong!! It would appear that it must be a .wav file, even though karaoke works with the .mp3 variety.
So, the correct process to get it to work is:
1. Convert the .mp3 file to a .wav file.
2. Make the key change and record.
3. Convert from .wav back to .mp3
4. Burn the disk
Seems it would be much easier if Keyrite would work with .mp3 to start with, but
whatever.
