1.6.4 Mod GUI background displaying as missing texture

[Collecter128]

Using the tutorials at

and

I was trying to make a combiner device in Minecraft 1.6.4, using the furnace as a base.

When you click the block to open the GUI, the background displays as the missing texture purple and black design.

 

The code I use to load the texture is:

public static final ResourceLocation gui = new ResourceLocation("MixerDivider", "textures/gui/CombinerasFurnace.png");

 

I have also tried:

public static final ResourceLocation gui = new ResourceLocation("MixerDivider", "/gui/CombinerasFurnace.png");

 

Substituting the texture of my GUI with the Furnace GUI works correctly, but I want to make a different one when the custom device no longer works like a furnace.

 

Important to note is that I had trouble getting the block texture to appear, so I used the tutorial here to fix it: http://www.minecraftforge.net/wiki/Eclipse#Fixing_textures_not_being_copied

I am not sure if this changes anything with the way the GUI should load or not.
