Here is a screenshot of the total war launcher, in Attila's mod configuration. 

When I press on the switches to activate the mod, it doesn't do anything, clicking on "Activate all" or "Deactivate all" also doesn't do anything.

If I press the reset button then it doesn't help. Restarting the launcher also doesn't help.

The mods are downloaded through Steam Workshop. 

The mod is called Medieaval Kingdoms 1212 AD. It's a pack of multiple mods, my load order is correct according to the mod maker and none of the mods that are required are missing.

That's about all I know, thank you in advance for any help with this. And I'll try to deliver any kind of info that is required to help.

Ok after playing the default game for a while. I can only turn on 2 mods out of 13 in the mod config.
