I'm temporarily uninstalling Dead Space 2, which I installed a looong time ago. The uninstaller said that I should de-authorize the game to be given one of my 5 activations back. The tool to do so requires my serial number, but I can't for the life of me find it anywhere.
Where might it be available? I did not buy the game through Steam, but it was a digital download of sorts.
Given that the game is already installed and authorized, can I extract the key from the installation somehow?
