Start up bug

[LuigiNotMario]

Hi, i recently downloaded forge mod and i run creepy salhack and wurst+2 on it but for some reason when i start it up it just does not want to start up. I do get thr loading screen when normally right after you would get the singleplayer and multiplayer buttons but after the loading screen it just stops and im back on my desktop like nothing happened. I already tried running other hacked clients and they word so i think this might be a problem with forge. I would really like some help please.
