I tried reading the FAQ about SonicStage software, and tried to uninstall it that way after things didn't work, got rid of the registry files and all. So I'm out of luck now, I have SonicStage 1.5 and I want to install 3.4, but I can't without uninstalling 1.5 fully. The reason I want to use the newer version of SonicStage is because lately my MD player (MZ-NE410 MDLP) has been transferring songs over, to have it run 2x the normal speed and skipping a lot. Thanks, Peter
