Hello, I am an Aero Glass for Windows 8.1 doner, I had my product registered and working, but when I re-installed Windows 8.1, I went to the glass8.eu machine code page and de-activated my key. I thought that when I re-installed I would get need a new key. But, the key that Aero Glass for Win8.1 gave me was the same. Now I cannot re-activate my key to use Aero Glass on my tablet. How can I re-activate machine code? I tried messaging bigmuscle directly but haven't heard anything yet. I'm sure he is very busy. It was my mistake to de-activate that key, but I am still using that computer so I need to re-activate it. Any suggestions? Thanks
