Yes, I've done both. I've been remotely troubleshooting while I've been at work, and I may have fixed the problem by reinstalling DarnUI, oHUD, and UIO. but I can't tell because I'm using TeamViewer. At the very least, I don't get a FalloutNV.exe has stopped working. I'll have to actually check when I get home in a few hours. It seems weird that DarnUI would be involved, but I swear every time it crashes I don't see the DarnUI logo pop up on the bottom left, and the few times it has worked I see it and roll over it with my mouse. Anyways, if it isn't a UI problem I don't think it's a mod problem because I've loaded all my plugins into FNVEdit and they all load correctly, plus the crash still happens when I have only F&L mods which were all installed as per the guide.
