I cannot start Forge 1.6.4 or 1.7.2. Clean install and downloads today from mincraft.net and minecraftforge.net (1.6.4, 1.7.2, 1.7.10). No mods, I click Play and it just CTD. Same thing happens on several PC's:
Nvidia GPU, Intel CPU
Intel CPU/GPU
AMD CPU/GPU
A couple mods my kids want to play haven't updated past 1.6.4 or 1.7.2 and won't work on 1.7.10.
Any suggestions?
