I have this Win XP Home Edition which I’ve been using since I bought my PC some 3 years ago. Thru necessities of re-installations during those periods, it accumulated scratches and lately displayed errors that failed to load some files. Too late now, cleaning the disc won’t help. I understand that what I bought from Microsoft is the license, so I should get a CD replacement (either FREE or with nominal fee). Note: I contacted Microsoft about replacement, but was told to buy new one? What happens to my license then? Anybody out there with same situation?
