Really Disappointing

So my Oled 512gb arrived today.. so excitedly updated everything and after looking at the store downloaded Forza 5 as I like a good racing game only to be confronted with a sign in box that I can’t sign into .. I have seen this appears to be an issue with Forza games going back sometime followed the instructions to try and fix it but sadly haven’t made it past the launch page..I have requested a refund but has kind of put a downer on my new purchase and am worried this will be the start of an unhappy relationship.. my son has one and loves it so maybe I am just unlucky with this game choice
