Cars/Packs and Credits not showing/loading........

…not very happy having purchased VIP and Car Packs and not a thing, nothing, not showing in cars, did not get my day one pack!!! Great game but feel a little robbed already

Any help would be great?

When DLC is successfully installed, the included cars are added to the Autoshow/Buy Cars menu and list for 0 credits so you can transfer them to your My Cars list for free (the first time for each model). Are you saying you installed the code but the cars are not in the Autoshow roster?
