I used the NMM for Fallout 4 and accidentally clicked the Download with NMM button when downloading a Skyrim mod. i usually install Skyrim mods manually and use BASH as my mod manager. I misclicked the warning screens that followed since I was watching telly at the same time. Now, Skyrim won’t even launch. What remains is to do a clean install of the game and all those 200+ mods I had.
I cannot recomend NMM to anyone. It’s completely useless, too unreliable and I’ve had problems with it before; I don’t know why I’ve maintained in giving it chance upon chance again. I will uninstall it and never use it again. My best suggestion is to manually install mods and sort them with BASH and LOOT. That process had my latest install of the game running smoothly for over a year now.
Good riddance, NMM. No more chances for you now!
