Je ne peux plus lancer mon serveur Minecraft

Bonjour

j'avais fait un serveur craftbukkit en 1.7.10, tout fonctionnait parfaitement jusqu'a la. J'avais ban ip et pseudo un pote car il avais fait le con, j'ai essayer de le deban mais je pouvais pas. Je suis parti dans banned-ips.json et banned-players.json puis dans usercache.json, j'ai supprimé son pseudo partout, j'arrête mon serv, le relance et plus rien le message d'erreus est :
