You didn't give us an error, or the code that is causing the error; seeing how the only thing you gave was "ForceDermaSkin", I can assume it's just a function that sets the skin in the gamemode. Replace the code with something like this:

function GM:ForceDermaSkin()
return "~ magic ~"
end

Also, welcome to Facepunch. I recommend you don't let it get to you every time someone doesn't share the same view as you.
