When i try use the pokefarmer, i got this message, but i log into BuddyAuth and the tab "Session" and there's nothing active, nothing to kill. what should i do?
You will need to purchase a pokefarmer key to use pokefarmer. Hashing keys is for all non buddybot products.
If you bought it recently, then you can contact the email support and explain it was in error, they might be able to switch up the key type for you.
