après avoir téléchargé modloader pour télécharger le mod secret room (j'ai suivi les instructions de minecraft.net sur la page web du mod), j'ai redémarré minecraft et celui ci me disait qu'il y avait un problème qui venait de modloader.

est-ce que quelqu'un sait d'où vient le problème?

merci d'avance

Tu utilises le modloader de la même version que ton mod au moins ?

Et il nous faudrait un screenshot de ton message d'erreur pour que l'on puisse vraiment t'aider

ok le voila :
