There are two questions:
1) I installed Hamachi, and it keeps saying "updating"... I turned off the antivirus and firewall, but nothing happens - what should I do? Is a restart important?
2) To play with a friend on a local network, do I need to buy 2 licensed copies of the game, or can we play on pirated versions? And is it necessary to play through Hamachi, since we are on a local network?
Thank you.
