Forge Crash Immediately On Startup

[Quaxk]

    I am having this problem where whenever I open up forge it crashes before the window even opens up. Can someone please help me with this.

Hi, i have the same problem.

When i start up the minecraft forged, it crashes.

It doesnt even goes to the menu. It just goes straight back to the launcher.

I looked for the logs, but i only have old ones and not from this crash :-S
