I need help getting Minecraft Forge working on my custom modpack?

[snipe you hard]

Hello. I am making a modpack in 1.4.7 using the mods Adventure Kit Mod, Bacon Mod, CustomMobSpawner, Mo'Creatures, Mekanism, Metallurgy Mod, Redpower, SodaCraft, Ether Mod, THX Helicopter Mod, Traincraft, and Twilight Forest, all in 1.4.7 and they work, too. I also have the coremods, NEI, codechickencore, and GUI API. I installed the minecraft forge (universal) in the modpack.jar i made in the bin folder. The version is 6.6.2.534, the newest for 1.4.7. I got it in the Dropbox public folder and got my URLs okay. I know the

hosting for my modpack works becuase my mods are being installed when I download the pack. My problem is

that minecraft forge, as well as any of the mods, are not loading. The box that usually appears saying

"FML is setting up your minecraft environment" isn't appearing. I know everything is installed correctly, so I don't

know what the problem is.

If you persistently try to solve this to no avail, try submitting a request for your pack here

And maybe watch the custom modpack tutorial again? I'm no expert on this, just trying to direct you to where you might find help.
