Skyrim mods and DLCs stopped working.

[UBER1337H4X00R]

I have played Skyrim for about 184 hours now about 100 of which i played using mods. I got the 3 DLCs about 4 months ago when I was about 130 hours into the game. I was doing the dawnguard questline when one day I loaded up Skyrim and found that none of my mods or DLCs were working. I made sure they were checked off in the data files list and that they were in the correct load order but it doesn't seem to work. I don't know what to do and I really need some help because this first happened about 2 months ago and the plugins still aren't working.

Have you verified the game cache? Go to your library, right click on Skyrim, go to the bottom and click on properties. In the new window, select the tab ‘Local Files’. Then you should find a button that reads ‘Verify Game Cache’. Click it and let the computer do its thing. Otherwise I suspect a redownload is all you can do.

Use BOSS it may tell you that you have dirty edits, also when did use last do an update of patches as they now been put on nexus and now follow the ESM's they were made for. Eg
Skyrin.esm
Skyrim Update.esm
Unofficial Skyrim Patch (still a esp but made to act like esm)
all the DLC's now have their patches the next line of order.

Yeah I already tried both numerous times and neither seemed to work. That's why I decided to come to the forums.

Then try BOSS as Kelvy suggested. If that doesn't work then give it a reinstall.

Just some help for you may not help but it is needed when modding
Mainly for cleaning dirty edits

It looks complicated but its not, writing the method is, but actually doing it is more in just clicking on item and programs do the rest.

Load order
Third party will show Skyrim.ESM.(BOSS, NMM etc) Steam will not (in game)
(new load order after last upgrade of packs)
Skyrim.esm
Skyrim Update
Skyrim Patch (USP)
Dawnguard.esm (DLC)
Dawnguard patch (UDP)
Hearthfires.esm (DLC)
Hearthfires patch (HFP)
Dragonborn.esm (DLC)
Dragonborn patch (DBP)
Other ESM's
High Res Texture Packs 1>3
Unofficial High Resolution Pack
ESP,s (Mods)

Programs required for mods to be stable in game(Or try to be)
SKSE (third party launcher for game)
Steam workshop (MODS)
Nexus Mods Skyrim (MODS)
Nexus Mod Manager (Needs the above to work)(MODS)
BOSS (Load order and dirty edits)
TES5Edit (Clean edits)
WYRE BASH (clean edits and makes Bash Mod to combine scripts)
and there are others

When loading mods subscribe in workshop but make sure they are not tick in box in DATA window, play through Helgen and save. Then start ticking boxes in DATA to make active a few at a time. Play game from first save if OK exit (DO NOT SAVE) tick some more mods on and play if no problems good to go.
Simular with Nexus Mod Manager, you must activate the mods before playing using the above method you should be able to limit problems.

Rule of thumb try not to have simular mods with same contents they may cause probs early in game or later.

BOSS will tell you your load order and it should be like I wrote.(you can move that order around yourself) (This is important to have correct). It also tells you if you have dirty edits ITM's and UDR's.
TES5Edit when you open it you will see a box it will pick up your ESM's and ESP's you have in game just click OK.

This will take time to complete (here on is a patience game)(More mods more time)
Once completed it should all load up on left side just choose Update.esm and right click on it.
Look for title Apply filter for cleaning and right click (Now for you will take forever make a cup of coffee) Nothing happens in page (no crash) just look at very top of page and it will ticking the bytes over.

Once completed the left column items will in colour.
Now using your BOSS list of files with dirty edits on it(2 monitors are great for this)
In TES5Edit now right click on SKYRIM.ESM and go down the list until you find one that is on BOSS list.

Left click on it and find REMOVE IDENTICAL MASTERS records and right click
A box with WARNING in it will appear wait and press OK (this is the only time it will show)
Bottom of right side page you will see it working when completed. Left click on file again and find UNDELETE and DISABLE REFERENCES and right click on that, again it will show bottom right page. You have to do that to all files in same order as written repeat until done.
Exit program and a window box will show with list of files you have cleaned just OK it all done for this.

Load WYRE BASH up this it will find Skyrim and it loads up all esm's and esp's, left click on one of the files There should be a build patch there, mine says rebuild patch (Dull in colour,which means I can't use it) as I have already done it. Sorry you may have to read up on, it's been awhile.
Right click on Bash Mod and find rebuild patch this must be done after every clean.(Realise where it was)
Not sure there is a help button bottom left of screen

Verify game always after cleaning steam will update and re install 5 files missing (66mbs)

When verify game one file is missing that means steam can not complete it until game is open then it finds your graphic card and it settings.
This message is not a problem and not to worry about it everybody gets it.

BOSS will now show bash tags but no dirty edits.

Double cursor bug
There is a fix on Nexus mods skyrim in topic BUG FIXES.
Interference from outside programs can cause this eg. Anti virus operating. If screen goes black or in game just move windows cursor off the screen press CTRL, ALT and DEL when windows task manager comes up just cancel it. The game will carry on as usual (there is no need to shut out of game (Game icon is at bottom of screen it is still active)

Black or grey faces is another issue but will not go into you need Creation Kit to fix properly.

There are many other issues that may crop up that have not been included but these are certainly the most discussed

I know its a long winded discussion but how else can you explain it, actually fixing the problems is straight forward and easy once learnt.
