We have a full guide on how to do that here. If the above doesn't work, we'd advise doing a complete, clean re-install of Hearts of Iron IV. Now re-subscribe to your mods and proceed.Delete a file called mods_registry.json.Delete the mod folder and everything in it.Find the folder where your HoI4 saves are kept (it's probably going to be in your Documents folder, some variation on C:\Users\YourName\Documents\ParadoxInteractive\Hearts of Iron IV - once you get there, you'll see folders for 'logs', 'save games', 'mod', etc.).
