Vogone Imports as WAV File Instead of CDG File

[Bossard]

I am trying to import a cdg file from my songlist folder to Vogone. It is from a DK Karaoke multiplex disk with the vocals in the track. I wish to remove them. After I select the file and open it, it imports it as a wav file even though it is a cdg file. When I click on the "low" button, it plays but I don't hear anything. What am I doing wrong?
