I am trying to install a 5 nights at freddy mod. it always pops up with "cannot install, this version of minecraft must be played at least one time"..This mod I got has a little small installer window asking me which profile to use, and I can select 1.7.10, 1.8.1, or Forge. I have another mod on Forge profile so I use that. But in my minecraft folder under forge 1.7.10 How can I get that fixed???
