if(FMLCommonHandler.instance().getEffectiveSide().isClient()){
		FMLCommonHandler.instance().bus().register(new KeyBindingHandler());
		KeyBindingHandler.preInit();
	}

Dont do this. use ur proxy for deciding if ur on server or client side.

You can't reference a client class in the server jar, so if your 'clientPlayer' reference in your main class extends EntityPlayerSP, right there is your problem - you have to put that kind of stuff in your ClientProxy and NEVER reference it directly unless you are in an @SideOnly(Side.CLIENT) class already.
