I figured out what the problem was, i had my GUI set to auto and it made it too big so NEI wouldnt show up a mod can close this now

thanks Torezu, but that is only a short term solution i still want the interface

i dont want cheat mode i want the interface i tried going to cheat mode and it still didn't pop up so i went back to recipe, the blocks at the side just wont pop up
