Is it possible to use this with Windows 8? I would really like to play but you guys stopped Windows 7 support so I don't know.

HannesC yep. that explains it.

Alright, so I am trying to open the Black Ops 2 game through Plutonium, and it is not working. I have moved the files to the right place, I also installed it again after uninstalling it. But it still decides to say "Not responding". I do not know if it is my computer or not. But it was working fine before this huge update.
