I want to play ic2. I install ic2 and put it to mod folder.
It didnt work when I click play, it didnt start the game, it took me right back to the Minecraft launcher. How do I solve that problem? When I use different mods except ic2, it still work. I dont put another mod in mod folder when I test ic2. I try another ic2 jar and it still doesnt work. Some people say use build 350 to solve it. What it is ? I dont find any article about build 350. My forge version is 1.6.4-9.11.1.965 and minecraft version is 1.6.4. 

After you suggestion, I install the 397 one. Minecraft does well without growable ores mod. Minecraft crash because a conflict happen between growable ores and Ic2. Is it a ID conflict? Do there have anyway to fix it? Think you very much
