I would love if someone could help me figure this out.

Ok look, i have made a modpack but, this is maybe a ticking screen issue. Maybe the Sphax PureBDCraft Resource pack is crashing it or one of your mods is making minecraft not function properly causing it to crash, maybe some mods you have included are mods that need mods that support it like Ars Magica needs Animation-API to function and work. You need to figure that stuff out and such. And maybe you can try to see if some mods are compatible with 1.7.10. Usually what i do is test the modpack with each mod, one by one to see if minecraft will work and start up well. So like first start MC with Tinker Construct, and if it works, go ahead and put another mod and see if MC starts up and functions properly

Yes i see a Twilight Forest 1.6.4 Mod Version! you need 1.7.10! Thats why and maybe a few other things
