I cant create a support ticket

Hello,
for some reason I cant create a ticket on the website. It just tells me to log in and when I do it goes to this website. I want to create a ticket because out of nowhere my livery design for the “Bugatti veyron super sport 2011” with 300k+ downloads (most downloaded design for the Bugatti) disappeared from my storefront and it looks like it was deleted from the game? My gamertag: I RXMPXGE I (i rxmpxge i).
Forza Horizon 5
Please help and thanks
