Fixing Scratches

[DLui126]

Hi! I tried to make a backup copy of my Ace Combat 2 but like, I found that after I let my cousin borrow it, it had some scratches on it. I didn't think it would matter, but when I burned it using Nero and the instructions on www.psxcopyworld.uk, it like just stopped at the Namco logo sign. I think it might be the scratch on the original cd, so, Does anyone know how I can fix the scratch? Thanks
