Dad/Newbie needs help: Minecraft crashes after adding Pixelmon 2.3.1

HandyGuy · September 23, 2013

I'm trying to help my son and any help would be very appreciated. I we downloaded and installed MinecraftForge 1.6.4. But when we add mods, Minecraft crashes upon opening. We installed Pixelmon 2.3.1.zip in the mods folder created after installing Minecraft Forge. We then added the Database folder into the main Minecraft folder. But, when we try to open Minecraft again, it crashes. I have attached the crash report and the forge.log.

Any help is appreciated

Thanks,

Guy
