I really don't know. Nothing that can be launched from the launcher doesn't open, and shuts down immidently. Help or advice?

My modpacks never open up into the actual program! I always click on the load button, the program begins to start, and I get the message that my Forge is setting up my mod packs. But then, after that, the program just shuts down before the Mojang symbol can come up! Help!
