Mod Problème extra utilities 1.7.10

[jules_fnsc]

Bonjour je joue sur des mods avec forge 1.7.10 depuis un certain temps et depuis que j ais installer le mod extra utilities le jeu ne se lance pas, ça me dit : Forge mod loader has found problem with your minecraft installation
The mods and versions listed below could not be found
ForgeMultipart : minimum version required is 1.2.0.336
The file "logs/fml-client-latest.log" contains more informations.

Je ne m y connais vraiment pas en programmation et informatique je joue juste de temps en temps mais normalement voici le contenu du fichier logs/fml-client.log
