Im a beginner Mod Pack Creator and im creating a mod pack for 1.4.7. I Worked on it for a bit and started minecraft. When i started minecraft it started to go through the normal Forge Loader. Then It had an error and told me to check the log. Since i have no idea what the problem is here is the log:
