I'm having problems with the forge, since I only have 1.7.10. Now I have to use the schematic in 1.8 and all the versions I've tried both 1.8-1.8.8-1.8.9 gives me this error how can I solve? The game crashed whilst there was a severe problem during mod loading that has caused the game to fail Error: net.minecraftforge.fml.common.LoaderException: java.lang.NoClassDefFoundError: cpw/mods/fml/common/event/FMLInitializationEvent Crash.txt
