First, have you got mods on?

If you do, these could be causing it, even if they all worked before. Try launching with only Forge and no mods. Or you try reinstalling, and if done correctly, you won't lose anything :-)

Ok... Have you tried taking all the files from the .minecraft folder and then uninstalling Minecraft completely and reinstalling it? I'm not real good with this sort of stuff... there also could be a Java update, try uninstalling Java and reinstalling
