Hi all,

I built a computer and purchased a copy of Windows 8.1 to put on it. I recently downloaded the same copy through BootCamp on my Macbook Pro w/ Retina. It won't let me activate it because I've already used the key. Is there a way that I can activate it again? It has the "Windows 8.1 Build 9600" thing in the corner. How do I fix this?

Thanks
