Hello
I'm trying to play Minecraft at home in a lan network. Because not every computer is connected to the internet (kid's PC), some of them are launched with a .bat file to change the player names.
Everything worked fine untill my son wanted to start playing with buildcraft. After a few hours of everything setting up, we started up Minecraft;
I can join the server fine, with no problems (Using the launcher, connecting to mc.net and all.)
However, my sons computer gives the error "This server requires you to have Minecraft Forge installed" when he uses the .bat to launch
His modloader.txt file stays completly empty.
When starting a single player world, no world at all is being loaded.
What could the reason behind it be?
