After a couple Tutorial, Helps and Informations, I write my problem here: So I updated from Beta 1.3 (no internet on my Gaming PC) to the 1.5.157. Before I updated, all my Mods worked fine, no problems at all. If I start now FO4 I can't load any of my old saves. Instant CTD. So looked for Fallout4Custon.ini. If I delete it, I can start a New Game without Crash. Old Save still don't load. If I add the [Archive] "Mod" into the ini, the game starts to crash again. I made a back up from my Plugins.txt, Loadorder.txt & DLCList.txt. I saw the change in the Plugins.txt, so i updated my NMM from 0.61.18 to 0.6.20. Tried to enable all mods (~ 70 Mods) -> doesn't work Reinstalled all Mods -> doesn't work. What should I do? Reinstall my entire game? Please help.
