sorry for the late response, to fix this, make a shortcut of the exe then right click it and select properties and in the Target Textbox you write next to the file path "-game hdtf" without quote marks and it should work properly.

that's probably because you replaced something from the base game, don't do that, this mod is standalone, that means that you don't need to have the base game installed, this mod already includes an exe.
