LUA Issue - DarkRP

Can’t seem to fix this error:

[ERROR] lua/includes/extensions/player_auth.lua:66: bad argument #1 to ‘KeyValuesToTable’ (string expected, got no value)

  1. KeyValuesToTable - [C]:-1
  2. unknown - lua/includes/extensions/player_auth.lua:66
    3. include - [C]:-1
    4. unknown - lua/includes/init.lua:104

At all.
Here is the player_auth.lua file I have:
http://hastebin.com/cuyamucare.lua

So, how to fix anyone?

seems like you or someone fucked this file
“settings/users.txt”

The users.txt file appears to be in a default state and not edited? Or am I a retard?

Discovered the source of the issue, forgot to transfer the entire settings folder to garrysmod thru FTP. In future I promise not to be a retard.
