Ok so. I have run Vanilla Minecraft Servers on our LAN party occasionally. I'm ok with these type of things.
I ran the Tekkit Server and try to connect to it with my own Tekkit Client using 'localhost' (that works in Vanilla if you are using the server computer) but now it tries to connect but it says
"Disconnected by Server:
You are missing the following mods:
(a lot of mods, basically all of them)" :'(
But it is not true. I can play them all with the Singleplayer. Please can someone help me. I seriously don't know what to do. ???
Oh, and I have Windows 7 64bit and Java 64bit
