Minecraft Forge doesn't open?

I installed Forge correctly, I even looked up tutorials to make sure that I did it right. I open my Minecraft and put the forge profile. But when I click play, the Minecraft launcher closes, and the game doesn't start up. It works fine when I play the "(default)" profile. What do I do to fix this?

Minecraft forge for the newest version of minecraft does no work, I looked everywhere and they haven't made a working version for it yet, You need to get forge out of your MC as soon as possible, any forge you download for your minecraft version right now is FAKE. So no mods that require forge until they come out with a real version of forge!

Make sure that if you have minecraft 1.8 not 1.8.4 because the highest the forge goes (for now) is 1.8
they both have to be the same. The mods you install as well have to be compatable with 1.8 as well
