I have an issue..when I start my game it crashes before hitting the title screen.

It is because of this line:

 

GameRegistry.addRecipe(new ItemStack(blockReactionChamber), new Object[] {"IGI", "IHI", "IGI",'H', itemChamberIgniter, 'I', Blocks.iron_block});

 

I have taken this out and it works just fine but I'm trying to make a crafting recipe with items I have made.

Another Error (in console) : AL lib: (EE) alc_cleanup: 1 device not closed

 

Any help appreciated thanks!
