Problem with activating mods. Errors

[trollberserker]

I have a Steam version of Morrowind and so far all the mods I've installed are working, but as of late, I can't activate or deactivate any mods.

I've tried activating them though launcher but I'm getting CTD when opening Morrowind or loading a save form main menu, when I open a launcher the mods I tried to activate before are unchecked. I've tried organizing my mods in Mod Organizer and Wrye Bash.

 

This is the message I get when trying to launch Morrowind though Mod Organizer:

 

This is the message I get when trying to activate or deactivate a mod in Wrye Mash:

Traceback (most recent call last):

I'm a technical dumbass and I have absolutaly no idea what's going on and how to fix it.

Shot in the dark; Is your Morrowind.ini set to "Read-Only? Right click morrowind.ini > hit properties and see if there's an X for the box "read-only". If not that, then by reading the errors, something is preventing morrowind.ini to be edited/backup. Anti-Virus / Firewall doing something? Add Exclusions to those folders/files. Good luck, TrollBerserker :)
