As I tend to re-install my system about twice a year, I was looking for a quicker way to do this. At present, I’ve got to install the original CD, then install SP2. I’ve managed to get hold of a newer CD with SP2, but when I install it, it won’t accept my licence key. After reverting back to my original method, I found that SP2 changes the licence code, so I tried that one as well, but that also failed. Any ideas as to how I can use the new CD with my original licence key? Or am I stuck with doing the long way around?
