OK, I'll try to explain my situation as best as I can.
Basically, I'm trying to set up a LAN game with my friends. According to the
Blockland FAQ, all I need to play LAN games is my full Blockland copy, so my friends are using Demo versions.
I set up my server, my friends are able to 'see' it and try to join, but they all get kicked out with a "This does not appear to be a LAN game" message. With various testing it appears they're able to connect to my computer - they see me in the LAN, ping me, they're even able to input passwords if I try to lock my server - but they can't join my game no matter what I try.
Could anybody please help me out?
