[2020] Mods from Steam not working.

Yes, what antivirus app do you use? Add CK3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.

You may need to add steam.exe and C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2020.13/paradox launcher.exe to that list.  

What antivirus do you use?  

Okay, did you add ck3.exe steam.exe and paradox plauncher.exe to the Apps Allowed Through list in its Ransomware feature?  

Please try the following:

- unsubscribe from all mods
- delete the folder Documents/paradox/CK3/mod/
- delete the file Documents/paradox/CK3/mods_registry.json
- delete the file Documents/paradox/CK3/launcher-v2.sqlite
- subscribe to a few mods
- run the game up and see if those mods are now available to you.

I hope that does it for you!
