Update 2: Solution found I'm an idiot. The problem was BSAs. I extracted them, and everything is now working. For bonus idiot points I've figured out why they were a problem. It seems the major error I commited while following the guide was that I accidentally downloaded the wrong version of Mod Organiser, I'm running 1.2.18. Thanks to everyone for their help. I can't believe I managed to get it that badly wrong.

Update So I've gone through and examined my mod installation piece by piece, like I should have done earlier and I've caught the culprits, though I'm not sure what's wrong with them or why. Interior Lighting Overhaul, Willow, Advanced Recon Stealth Armor, Spice of Life and Courier's stash integration. With any of these five enabled I get the access violation error and the game won't start, without them enabled it'll start just fine. If anything about that list leaps out at anyone please let me know, I'm going to investigate further.

Didn't work. I re-verified, which had some strange effects on mod organiser. I ran the game first outisde of mod organiser, then at the default profile, which still works, and then in the Fear and Loathing profile, which has spontaneously sprouted haphazard categories and failed to start as per before. Edit: Disregard what I said about the weird effects, I'd apparently just hit the sort to categories option by accident, now looks like I left it again.

Yes, I ran the game through steam before I got started. I also didn't delete the main executable in the first place if that helps at all. I used the process for reseting my New Vegas install described in the guide, deleting most things in the game directory and data folders, and using steam to verify game cache integrity. I also ran the game a couple of times during the earlier stages of the guide, through MO and shortly after installing the UI mods, and it was working just fine. Edit: I had been running FNV4gb before as well, but I deleted that and retrieved the original exe from the exes folder and dragged it back into the game directory before verifying, in case this detail is important.

I'm not big on posting problems to public forums, but I'm at my wit's end on this one. Recently I decided to nuke my New Vegas install and start again using F&L. Two days of intensive downloading, sorting and double-clicking later I got most of the way through (still haven't made any attempt at DDSOPT), but in testing what I have, I've hit a problem I can't resolve. The game doesn't start, I get the "Fallout New Vegas has stopped working" and nothing else, which in my experience is usually a load order issue, so I ran it through FNVedit to try to figure out where the issue was, but FNVedit loads and edits my install without giving problems. I've run my load order through LOOT repeatedly, but it spits out exactly what I'm using. I've got no indication I can point to of where the issue is and even less idea. My next best guess would be an INI issue, but everything worked just fine at the guide's recommended test point with the exact same INI settings, so I'm pretty sure it's not that.I can switch back to the default profile, and the basic launcher, NVSE and FNV4gb all work just fine with Mod Organiser there. So before I go for anything more heartbreaking or drastic to try to sort this out, I was hoping maybe someone here had some experience or pointers. I've checked the forums, and at the risk of looking very foolish when someone points it out, I can't find anyone having this exact issue, I really hope it's just something small and dumb I'm overlooking here.

As an addendum, it's my first post here, so in case EssArrBee reads this, thank you, F&L is invaluably helpful and I hope I actually get to appreciate the final product soon.
