Black screen after logo

[Frikken]

I need Forge to run some mods that I use as they are no longer compatible with Modloader. So I decided to get Forge and install it. I used Magiclauncher to install mods, I deleted Modloader from it and put Forge all the way at the top. It says 1 error but usually that isn't a problem for me. However, when I try starting Minecraft I get a black screen after the Mojang logo. Even if I put Forge as the only mod in there I still get it, even installing manually did not help.

My client has the latest update and I have the latest release of Forge, so I don't think it's a problem with anything being outdated.

EDIT: I've searched other threads to a fix to this but nothing has helped.
