trouble with missing masters, sorry to bug you all.

[gnome59]

Dear Nexus Community;
I have several missing masters! And I don't understand why? Some are named after mods I have downloaded,
At which how can they be missing if I never had them and how do I obtain them now that they are missing?
This is the list of missing Masters I have;
Madrock-999-01.esp
DLCworkshop02.esm
DLCRobot.esm
NorthernSpringslodpatch.esp
JonsMod.esm
Armorsmith extended.esp
Armorkeywords.esm
Postwarpowerdisplays.esp
Please Help me, so I can get my Fallout4 running smooth again!
I am also having performance issue's, that for the first 8 months of playing I didn't have.
Freezing, lagging, crashes at times, Etc. I love playing, and yes I am new to this kind of gaming..
But I guess at 62, - but I am willing to learn!, I'm a little behind the learning curve, on how this all works together..

yes i have searched every file to see if they are here,, and nope i still dont have them
PLEASE HELP, I'M DESPERATE!
Thank you
Gnome59

These are the ones I know:

 

DLCworkshop02.esm >> Contraptions Workshop DLC

DLCRobot.esm >> Automatron DLC

Armorsmith extended.esp >> Armorsmith Extended

Armorkeywords.esm >> Armor and Weapon Keywords Community Resource (AWKCR)

 

Make sure they're in Fallout4/Data folder (along with their assets i.e. DLCworkshop02 - Main.ba2).

 

By the way, you can use a mod manager to manage your load order.
