Alright, I fixed the problem.
It’s not a game problem, I had the same issue with War of the Roses and some other games. Here’s how you fix it on windows 7.
Go to Control Panel -> Network and Internet -> Network and Sharing Center -> Set up a new connection or network -> Connect to the Internet -> Select do it anyway or something like this -> Select Private.
Enjoy, now the game works.
Apparently the problem is related to your computer LAN card drivers and/or your modem. Opening a new connection to the modem should help. Try it out…
Also, when you set the new connection DON’T have it as a network, have it private.
Let me know if it fixed the problem for you too-
