It shows in my transaction history that I purchases welcome back free psp game 1 but then doesn't show the game that I wanted to buy which was pursuit force cuz it disappeared!! effing ripped me off for a $23 purchase.. I'm ticked!
If you go to the "services list", and select "scea promotion", then select "welcome back: free PS3 game 1", then "select Content", You should get to where you need to be to download what you want.
Hope that helps.
