Minecraft Forums

I have updated my forge to 1.8 to test out some 1.8 mods. However, when I launch forge, I keep crashing, and the game never starts up. I have installed forge into a clean .minecraft with no mods installed prior to startup. I have downgraded java to seven, reset my entire .minecraft folder, and still I cannot find the reason. The Crash Message is below.

I Figured out that problem, and yes it is because of the fact that I had installed FML and not actual Forge.
