Hello, thanks for taking your time to try and help me
Description: I can start my tekkit and get into the minecraft main menu but, when I try to join my friend's server my minecraft crashes me to the technic launcher. Also when I try to join single player it just stops at "Building Terrain." I have tried to change my memory but it seems like it doesn' do anything. The parameters for the server is "java -Xmx3G -Xms15M -jar Tekkit.jar nogui pause."
