Perhaps many other people have tried this without succesion, but does someone know how to play via LAN? Could it be possible that the versions have to match or something? On my computer, I've got a hacked version, on the laptop of my little brother we have the normal CD. We tried it with using the files as shared on local network, no success. If someone made it through, please, let me know.
Yea... Connect to the same router.
