install hamachi, and you can find it in filehippo.com. One of you must host the game. How to configure? Watch this video. http://www.youtube.com/watch?v=Sfr8PoJ3mOQ
...after that, disconnect your internet connection first, run nbalive08>play online>create a new game, your game ip now should be hamachi's(not 192.XXX.XXX.XXXX - if you get this ip, then you do not follow the instructions correctly on youtube). Minimize the game by pressing the ALT+TAB keys on your keyboard, DO NOT EXIT THE GAME or hamachi's ip will be gone. Reconnect your internet connection and give the game ip you when you create a new game in the online mode. That's it. Enjoy..
