We need your log. Without your log we can not help you Is that hard ? ...

bin/Minecraft.jar -> net.minecraft.client.Minecraft.java -> public static File getMinecraftDir() { if (minecraftDir == null) { minecraftDir = getAppDir("minecraft"); } return minecraftDir; } You must change this code. But change the main minecraft class is bad. You can use java reflection to modify this field, is that FTB's Launcher does : https://github.com/Slowpoke101/FTBLaunch/blob/master/src/net/ftb/mclauncher/MinecraftLauncher.java#L185

I'm not sure it will work, add "--nogui" at the end of your batch file. Exemple : java -Xms1024M -Xmx1024M -jar minecraftforge-universal-1.5.2-7.8.1.737.jar --nogui

Like VengeanceSoldier said, read the tutorial.

What other mods have you installed ? Ladder work for me with the last build (7.8.1.737)

If you get a error with "java.lang.NoClassDefFoundError: net/minecraft/client/something" it means that you install a mod incompatible smp I hope it can help you fix your problem alone (some modder are too stupid to use @SideOnly(Side.CLIENT) ...)

Wrong section, post in the support : www.minecraftforge.net/forum/index.php/board,15.0.html java.lang.NoClassDefFoundError: net/minecraft/client/gui/GuiOptions You have install a client side mod, it can't work in smp, this mod is probably GUI-api, remove it And run your server with a batch script (.bat on windows, .sh on linux) java -Xmx1024M -Xms1024M -jar minecraft_server.jar

put it in .minecraft/lib

public void load() { This is modloader method ... Try @Init public void load(FMLInitializationEvent event) { }
