I tried again and I can't open the forge file. I am on a mac. It says "We appear to be missing one or more essential library files. You will need to add them to your server before FML and Forge will run successfully.java.lang.ClassNotFoundException: net.minecraft.launchwrapper.Launch"

Any Idea what this means? What should I do?
