Forge versions 1.8-11.14.4.1450 and 1.8-11.14.3.1521 not launching properly

kaina122 · October 29, 2015

Hi. This is my first time attempting to mod Minecraft without using a separate modpack launcher. I installed the latest version of forge and managed to get it running, however, when I came back to the game later, after adding some mods into the mods folder, I attempted to launch forge again and it ran into an error and failed to launch. This is the latest log report of the error:
