I was trying to make a 1.7.10 server and ever since I tried to make that server my game when I try to load the game this happened
The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: cpw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: net/minecraftforge/fml/common/event/FMLInitializationEvent
