Hey everyone, I'm in need of help... Here's my history. I had a Dell computer running windows XP (I don't know what version), a few years ago. That computer died, and we got an iMac. The thing works fine, but my brother and I are gamers, so of course we had to buy leopard, and thereby Boot Camp. We installed Leopard, and started boot camp. I went through the whole installation using my version of Windows XP from my computer a few years ago. As far as I can tell it's just Windows XP Home Edition. It works fairly well, but there are a few problems. First of all it won't detect any speakers or sound device, so I have no sound in windows. Second, and more importantly, I tried to activate my windows, so that I could download the Windows XP service pack 2 that my computer keeps telling me I need. I go through the wizard until I have to put in the product key. I found the only product key I could, which was on a sticker on my old computer. It says "Windows XP Home Edition....Product Key: etc..." I put in the product key, and click continue, and it says that my key is incorrect. I have no idea why it would do this. Will it not work if I've already had this OS on another system? Do I need to buy an entirely new Windows XP? I would much rather be able to use this one, since I'm typing this message on Windows Anyway. This is alot more complicated than it needs to be, I think, so any help is much appreciated.
