So, I have been working to create my own custom modpack for a while now. Most of the mods are from (https://www.youtube.com/playlist?list=PLSUHnOQiYNg3N9VfUb40gM1UsD4E09Vhh) and (https://www.youtube.com/playlist?list=PLSUHnOQiYNg38N8I74dnXkr_w5GVOWBGD). All of the mods are in 1.7.10, and they all work together without NEI; but as soon as a launch the game, it brings me back to the launcher with a weird Game Output window. I would really appreciate the help! (I also tried TMI and that crashed my game)

Sorrry, but how exactly do I do that?

Here is the copy-pasted text, if that helps:
