Help Needed

Recommended Posts

this doesn't belong in Bug Reports, as this is not a bug with the Launcher.
Moved to Platform Pagoda for discussions about custom modpacks


Exception in thread "main" java.lang.NoSuchMethodError: joptsimple.OptionParser.allowsUnrecognizedOptions()V

it's impossible to tell what this error is. post your link to the modpack so others can see how you set it up
