Minecraft Forums

So, I found a mod called the MenuMod (Not the main point.) that requires forge. of course, I open up MCPatcher, install mods and stuff (Mods include SinglePlayerCommands, Forge, and the MenuMod.) and I patch Minecraft. So, I start Minecraft up, log in, and something says "FML is setting up you Mnecraft enviroment." And that loads up. Then, I wait for the Mojang screen to come up. It dosent, unlike usual Forge problems. So I look up "Black screen on Minecraft using Forge." and no-one has the same problem as me. I force updated and re-tryed. Still, "FML is setting up Minecraft enviroment." Its done, and again, I get a black screen. I cant deal with it.

I've manually installed forge with the steps on the forge fourm correctly, and I still get a black screen.
