Probleme installation Dofus

Bonjour,

J'essaye d'installer Dofus sur mon pc sous ubuntu , après avoir rencontré plusieurs problèmes que j'ai réussi à résoudre, je bloque.
L'updater a marché et j'ai le bouton "jouer" etc... sauf que quand je clic, le message d'erreur "Le jeu n'a pas pu se lancer ou ne s'est pas fermer correctement" et voici les détails :
Error : U0404007F
Le jeu n'a pas pu se lancer ou ne s'est pas fermé correctement.
