I just looked at my mail archive. Apparently, I bought a Windows 7 Professional for you and for Flora. I'm pretty sure Flora received the DVD (Noelle mailed it), and I assume that you also received a DVD. So, you should have the DVD and associated packaging, and there must be a key associated with it somehow. Assuming that it was activated at some point, I'm not sure how you could have activated Windows without it. (If I remember correctly, I didn't open the package with the DVD in it so it should have had the original key in it.)
