So I've been using mods for Fallout 3 for a while now, but this startup crash is a strange one. I can deactivate all mods and leave either just Fallout3.esm on by itself or with the official DLC and it still crashes. I was just trying to start a new game but it crashes at the first slide you see when the game starts up. I do have ENB .150 installed but I had played previously with it. The only thing I can think of that might have caused an issue is when I tweaked the Fallout.ini for the Pipboy 2500. I have made Fallout 3 large address aware (3gb enabler). I already played the game modded with this. Previously I had played the game with different mods, with the same ENB installed and I experienced no crashes. My game began to crash on startup after I: 1. Installed new mods (mostly textures, a few requiring FOSE (flashlight), and a vats and fast travel disabler, Pipboy 2500) 2. Tweaked ini settings for Pipboy 2500 The game would still crash on startup even if: 1. Enabled Fallout3.esm only 2. Reset ini (by deleting and then starting up game) If anybody has some tips or advice for troubleshooting, please let me know. I'm not sure where to go from here. I can post load order if necessary, but like I said, game is not running even with just Fallout3.esm enabled.
