Hey guy's! I made a modpack with 51 mods but i've got a problem. I can't start the game. It keeps saying something like:

The coremod ic2.core.coremod.IC2core does not have a MCVersion annotation, it may cause issues with this version of Minecraft

 

I will post you the log maybe someone can help me
