In fact, all of my mods are related to the UI or basic things.
I have no weather mods, and Seven Sins is the only ENB I have installed.
The load order seems to be correct, and there are no conflicts. LOOT, NMM and FNVEdit say there's nothing wrong with my plugins. The game also crashes when I try launching it through NMM or Steam.
Running nvse_loader and FalloutNVLauncher.exe as an administrator and normally didn't work. Now the game will work up until the copyright screen (With the Bethesda logo) and then crash with a 'Fallout New Vegas has stopped working' message. I uninstalled NVSE and reinstalled it, and it only made everything worse. I figured out that using FalloutNVLauncher.exe as an administrator *worked, and it fixed Steam as well, but nvse_loader still didn't work (even when ran as an admin). Black screen, then back to the Steam Library. The game simply stopped working - wether I used Steam or nvse_loader, the game crashed right after the initial menu (The one with the Play, Options, Tech Support, etc.) without any error messages. Everything was working nicely, until I installed an ENB ( ).
