I used a code I got from a set of mini games to redeem a mclaren SLR in GT PSP. I entered the code into my UK network account and downloaded the car but its not in my garage. I tried redownloading to no avail. Am I supposed to do something after the download/install? I have a new icon under my games folder with a car rendering with a cloth halfway off of it. Nothing happens when I select it besides a "This game cannot be played" message.
