Custom Modpack Crashing on Startup

[cooldude_]

So, I've made a custom modpack for me and my friends with around 80 mods for Minecraft 1.7.10. Whenever I try to launch it, the game just closes before even loading and returns to the Technic Launcher. I don't think it even generates an actual crash report but in the console it says this:

Question, your modpack is called Project Giraffepack?

[AetherPirate]

Your Forge version is quite old. Update to the latest for 1.7.10

After updating that, you will need to update many of your mods. Most are very out-of-date. I began testing after updating Forge, but after being prompted to update various mods 3x times, I will leave that part to you.
