Ok a friend of mine is having this problem when making a character. Its weird b/c all my other friends can play it with np. He deleted the game's folder 1000 times and downloaded the updated one, with it was no good. I also deleted my item's folder and re-did them. Still same. Any ideas¿? btw: I created a character for him but he can't see the Inventory pictures, and when he equips a sword, he get the error.
