SOLVED - My modpack crashes when I launch it

[Inglonias]

Solution: Do not use the version of Forge that comes from the installer. Use the Universal version.

 

I feel stupid having to ask this, but here I am. First modpack, fixed vanilla launch issue only to find this one. I click play, modpack begins loading, and then crash.

Technic Platform page for my modpack: http://www.technicpack.net/modpack/soft-landing.614416

Error on launch:
