AoE2 still doesn't work

So when I changed the launcher applications's names it just updated my game to add the correct ones but 1 or 2 files were still missing. The thing is that I never changed the game before this problem. The worse thing is that I really loved this game and was very dedicated to it. :( (Btw I might make some gramatical errors but english isn't my native language, I just learned english from memes, the internet and games )
