I'm am currently working on a MOD and I want to add in an EMC value for this item. I am having a few issues, as listed below: 
  
I cannot find a specific API for the projectE mod (I am currently using the files that came off of the github page) 
  
I have tried the following code implementing some of the proxy files found in this zip file but it gives me an error when it tried to add a value to one of my blocks: 
Error: 
  
  
  
  
The error is caused by this line of code: 
public static IEMCProxy proxy; <-- The implementation of the proxy 
proxy.registerCustomEMC(new ItemStack(ModBlocks.metadataBlocks2, 1, 0), 2048); <-- this one returning null 
Is there something I am doing wrong? Any help would be appreciated.
