Well, Cayne, that's exactly the point.
Their rules are that the same code from the same CDROM set shouldn't be on two different systems. I sort of dislike Microsoft, I ABSOLUTELY HATE their validation requirement, but I won't cheat them. I have to go with Nemesis on this one.
I've got two kids. I built them each a pretty decent rig (at the time of building). I mean, they're kids; my kids, and share the same home network with me. But each one has his own set of WinXP source CDs from which it was loaded. That COST me, but it's legit. I hurt, but I sleep well.
