how do i detete my music library in hercules instinct

hi can anyone help
i recently purchased the hercules instinct running the djuced 18 . i analised and added my entire music library to the instinct but had some errors and would like to delete them from only the instinct and obviously not my laptop. i took out the program and re-installed it but all the library is still there along with faults. does anyone know how to satrt all over from fresh without the loss of my actual music library ... i bet this is obvious but i havnt got a clue lol thanks
