Game not redownloading

Hello Coalition
i bought gears of war 4 over year now for the pc i have been playing and even have the season pass and every thing that comes with it. A couple months ago my computer crashed and i fixed it. i went to redownload gears of war 4 and it didnt appear in my microsoft library, i called microsoft and tryed talking to them about it but they told me it wasnt their problem since i bought the digital code though amazon. I tryed contacting amazon about it and they never got back to me. i would like to be able to play again. have you guys heard of this happening before. i can be reached at Jason.brn1@gmail.com

thank you
forrest riley
