Ok, so, I tried reinstalling and all, but it still doesn't work. Here is the entire process I did:
>Uninstall HoI4, purge anything pdx related on PC.
>Delete TNO files and get new ones.
>Install using CODEX iso file.
>Start the game, get one save done as well.
>Install the pdx launcher.
>Using mod tools, create a TNO folder in the mod folder of pdx files.
>Copy everything but the .mod file (the launcher created one inside and outside of the TNO folder already) to the mod folder from the zip of TNO files.
>Manually start HoI4 as launcher doesn't work
>Starts loading, all the tips, pictures and UI elements are TNO
>Crashes on 4/10 of the progress bar with the map loading error
All of this is the same as before.
