Résolu Attack of the B-team 1.0.13c

Bonjour,
je rencontre actuellement un problème lors du lancement de Attack the B-team sur le technic launcher.
Le launcher disparait puis réapparait quelque seconde plus tard. J'utilise la version 1.0.13c sur windows (ça marchait en version recommandée).
Voici les logs :

Merci de vous être intéressé à mon problème

 

A oui j'y avais pas pensé: je suis un peu à l'ouest parfois :)
Ça marche correctement maintenant.
Merci beaucoup
