    posted a message on I am unable to start my custom modpack on the curse launcher

    Alright, so I created a modpack on the curse launcher, and it doesn't seem to be working. When I start the modpack everything goes fine and it opens the minecraft launcher. Yet when I push play on that, it goes for minute, then stops while giving me the option to push play again, which only repeats the process. It doesn't crash but comes up with this error in the game output:
