The problem is that its my mod and i have totally no clue what to do

I didnt found anything strange in my coding.. Maybe these codes could help you to help me:

 

MainRegistry.java:

package com.roy301.Main;

import com.roy301.creativetabs.IECreativeTabs;
import com.roy301.item.IEItems;
import com.roy301.lib.RefStrings;

import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.SidedProxy;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPostInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;


@Mod(modid = RefStrings.MODID, name = RefStrings.NAME , version = RefStrings.VERSION)
public class MainRegistry {

public static final int WILDCARD_VALUE = Short.MAX_VALUE;

@SidedProxy(clientSide = RefStrings.CLIENTSIDE, serverSide = RefStrings.SERVERSIDE)
public static ServerProxy proxy;

@EventHandler
public static void PreLoad(FMLPreInitializationEvent PreEvent){
	proxy.registerRenderInfo();
	IECreativeTabs.initialiseTabs();
	IEItems.mainRegistry();
	CraftingManager.mainRegistry();
}
@EventHandler
public static void load(FMLInitializationEvent event){

}
@EventHandler
public static void PostLoad(FMLPostInitializationEvent PostEvent){

}
}

 

RefStrings.java:

package com.roy301.lib;

public class RefStrings {

public static final String MODID		= "itemexchange";
public static final String NAME			= "Item Exchange";
public static final String VERSION		= "1.0";
public static final String CLIENTSIDE	= "com.roy301.Main.ClientProxy";
public static final String SERVERSIDE	= "com.roy301.Main.ServerProxy";
}

 

ClientProxy.java:

package com.roy301.Main;

public class ClientProxy extends ServerProxy {
public void registerRenderInfo(){

}
}

 

ServerProxy.java:

package com.roy301.Main;

public class ServerProxy {
public void registerRenderInfo(){

}
}

 

Ok i renamed the serverside in the refstrings and it works now but i didnt know i have to accept the EULA

It works perfectly now thank you!
