Swap Magic/MVP Baseball 2005

[Cactus Drags]

MVP Baseball came today, so I fire up Swap Magic and get ready to play...no joy. I get the message "This is not a valid PS2 disc." Cheaky bastard thing. Anyway, I've searched on the net for possible resolutions, but they all seem to be dealing with people using copied games. Can't seem to get anything from the official site, but I know swap magic works with import games (works fine for NCAA 2005 for example), as it's advertised. I'm using v3.3. Any have any idea what's wrong/what I need to do?

EDIT: Nevermind. Just remember to lock the cd tray after inserting the game, guys
