From the developer:
This Program cleans the errors from most CDG files
The Program replaces the files even if Zipped! So, make sure you have a backup of your files! Put two songs in a folder that you create (use songs with errors), and run the Demo on them, then import and play the new imported songs and see if it fixed them.
The program cannot fix all errors, but it does fix most.
