How is your CD disc damaged? Had a PS2 disc badly scratched by my six year old son and it would not load giving an error message. Used a typical kitchen 'cream cleaner' to polish it in a movement from centre to outer motion then buffed it up with a clean cotton cloth and it works ok now. Bit of a risk I know! Try the free program first and if that recoveres most of your files, then, try the manual polishing to see if the CD will play all of the files.
