Hello ! I have a Windows 7 Home Premium OA edition. The PC stopped working for some reasons, I had to format it and re-install Windows with a different version. Since my key isn't working with the actual version I have, where could I download a correct W7 HP OA 32bit version ? I tried to add my activation key on Windows' website, but it says my key isn't recognized. Obviously all the activator I found on the Internet aren't working. What can I do ?
