To add the PlayStation®3 platform to this service account, you must first either purchase the digital download, or apply a registration code through the Sony Entertainment Network.
Please note that PlayStation®3 services are not accessible through this website.
Upon completing registration, the game can be installed and played as normal on your PlayStation®3.
Alright, fine. I go onto my PlayStation Network, and enter the registration code that came with the game:
The code you entered may not be correct or may no longer be valid.
Please check your entries.
I also logged directly onto the Sony Entertainment Network web site, and see nowhere to enter a code...so, I guess I'm just supposed to wait a couple of days?
