Note from developer:
To convert your songs from previous versions, just convert all your RAW samples to WAV files (with .wav extension). No other changes have to be done.
If you are having problems loading WAV files, try load/saving any problem WAV files in something like Audicty (freeware) or Sound Forge. The WAV file loading code just uses the most common format and may not be compatible with non standard wav files.
