Hello Dallas
About North Carolina, you have to install first : Bismark.
And, after and only after, you install NC ( North Carolina ).
If JSGME say:
"USS_NorthCarolina.lua" has already been altered by the "Bismarck" mod.
"AutoGunSounds.lua" has already been altered by the "Bismarck" mod.
"CannonSounds.lua" has already been altered by the "Bismarck" mod
You do :"yes" and you can, normaly, open DCS.
Bye.
