When I try to /ar hook I get an error, and I can't get the stats to work with Autorank? I downloaded the stats plugin from bukkit, you can see the error code below :) Both versions are downloaded from bukkit's website (The standard download button)

If the problem is wrong version, please link me to the correct version

Use the versions that are on Spigot, those are updated ;)
