I would highly recommend not doing that...

Make sure you're running the version of forge required for the mod (no greater mind), the latest version of the mod, and try removing fastcraft.

If you have configurations for mods that you don't need you can check in  and delete those that you don't want (they'll be regenerated when you play next).
