User blog:TheTntFurnace/Can't Get LAN to work

I cannot get the LAN to work with this mod unfortuneately it just says java.net.connectexception timed out. This even happens in vanilla minecraft but the Minecraft Forum isn't replying to my thread :( My sister has a mac and I have a Windows and we turned off the firewall and both tried hosting but no luck. Oddly enough on some rare occasions we have been able to play with firewalls enabled. I am using the Technic Launcher modpack for Lotr btw.

Help would be much appreciated, Thankyou
