[black hawk]

Hello there. It's been quite a while since I last checked in. Anyways, maybe someone could help me on this. I would love to play Full Spectrum Warrior on LAN with my friends, but the game simply keeps giving 'Network Error'. It's not a retail version I think. This game was apparently made free by the US army for a time period, and these tech magazines got hold of it. Could the version be a problem here?
