Issue with Enabling Mods in Game Settings

Hi,

I’m having an issue with enabling mods and custom content in the game. When I turn the option on and restart the game, it doesn’t save and the setting is unchecked again when I launch it. Because of this, I can’t use any mods at all.

I’ve tried turning it on a few times and restarting, but it keeps happening! Also, I’m encountering Error 21 when trying to save the game.
