Hey Ashi, seems you got your problem sorted but here's an alternative 4GB patch that I've been using: http://www.ntcore.com/4gb_patch.php

I'm a Mod Organizer user & this helped me out greatly without a bunch of incompatibilities, launch errors or sorting out conflicts. Used it ever since since I started modding FNV & it has worked pretty well so far.

@Enomer yeah the ENB mod was installed but no DOF or anything was showing up in the Enb Shift and enter text, but i got it full working now so it all good now thank god
@Unquieterpig yeah i always launch it in admin mode just to be on safe side
@aerystmd hey dude yeah im a FOMM user but il have to have a looksy at it, might save me any future problems if i have anymore, thanks once again for all the tips and advice guys, i can now get 7 days worth of FONV before FO4's release

@Ashi Itachi, no problem, glad to help. & although I did mention that I use MO, NTCore 4gb patch isn't exclusive for it. The patch modifies the FNV.exe itself so therefore making it simple to use, without any files added.
