Since I have seen the same issue I am encountering stated multiple times in the comments, I figured a more polite approach to inquiring would be through a calm forum. Following your instructions, I successfully implemented the mod.

However, the mod crashes immediately at the splash screen. The only thing I can think of, is that something in Empire at War Remake received an update that isn't shared by this sub mod, making them incompatible.

To be clear, the version I have is Empire at War Remake: Galactic Civil War. If this is the wrong version, I'd appreciate some assistance in the matter - and hopefully it helps some other players as well.
