Yes, I actually did. Is it possible download an older version and try again?

I did, and it did not help. I've also tried manually setting plugins.txt to non-read only. It only helps to a certain degree if I fill the txt with hand and then run from f4se exe not from nexus. (normally I link f4se to nexus and use it).

Two days ago (today is 19/03/2016) Fallout 4 was working alright, and now when I launch fallout through Nexus Mod Manager (NMM) and load my save, it says mods are missing. I'm using F4SE, and I've tried without it. I've tried creating a clean game and no luck. I've tried uninstalling NMM and deleting the leftover files. I've tried uninstalling Fallout 4 and deleting leftover files. I've tried uninstalling both NMM and Fallout 4 and deleting leftover files. My observation is that plugins.txt file gets set to read only whenever I launch Fallout 4 so I've googled the problem and found out that changing the name of launcher and using Fallout4.exe as launcher will solve the problem, I've tried that and it did not work. I don't know what is wrong with Fallout 4....
