PaidRanks Config Help?

Hello, I am currently trying to configure the plugin "PaidRanks" to work on my server but I cant seem to do it correctly. The config is below:

Code:

DefaultPaidRanks:
  #Format =    <rank>:  Example below.
  #Required      Price: <price>
  #Optional      permission: <permission>
 
  #When true it will use /rankup
  Enabled: false
  #There must be a permission here.
  Permission: paidranks.normal
  default:
    Price: 100
    #This one is optional
    Permission: paidranks.normal.default
  # ^^^^ These are examples of permissions with groups
  #vvv it can look like this too. But it will use the Permission defined at the top.
  moderator:
    Price: 200
 
NewLadders:
  #Format = <ladder>:
  #Required  <rank>:
  #Required    Price: <price> Example below.
  #Optional    Permission: <permission>
 
  #When true it will use /rankup <ladder>
  Enabled: false
  #The ladder name
  EpicLadder:
    #There must be a permission here. This is the main perm for the ladder
    Permission: paidranks.ladder.EpicLadder
    #This is the group
    donator:
      #This is the price (Required)
      Price: 200
      #This one is optional
      Permission: paidranks.ladder.EpicLadder.donator
    # ^^^^ These are examples of permissions with groups
    #vvv it can look like this too. But it will use the Permission defined at the top.
    donator+:
      Price: 300
 
# These lists are ordered from lowest rank to highest rank.
# If you change default make sure you change it to the group
# that your users enter when they join the server
# or this plugin will not work. Group names must match
# the group names in your permissions.yml file
# or ranking up will not function properly.

I've been trying to configure it properly for the past hour, but to no avail. Does anyone know how to configure this properly?
