Is this possible at all? It wouldn't seem so, since the activation key is bundled up with the installation, so if it freezes, the whole thing does. I successfully installed it on one computer (and even looked around for the key to be displayed somewhere), but my laptop doesn't like these keys for some reason, and this is really the machine I use most. And what if I wanted to put the game on a computer that doesn't connect to the internet?
I suppose I shouldn't complain, since it's free. At least my bro will get some use out of it...and maybe he'll let me play on his computer, since I gave it to him. :-P
