Got the rosters by following the link you provided. Thanks!

I just deleted the app and re-installed after exporting and reimporting my data. Same error message. I'm not sure what else to do.

I tried that and I tried shutting down the phone and restarting, neither worked. I would just delete the iScore app and reinstall but I don't want to have to pay $9.99 again. Any other ideas?

Just running on the iPhone, not the iPad. Thought at first it was an iTunes store issue but that's not the case (I'm able to download other non-free apps). Any other thoughts?

I'm having trouble with adding the MLB2012 rosters for the iScoreBaseball app on my iPhone. I used it last year, no problem. Tried to get the update and I get this message: You can't purchase this. You must purchase the app that this item is for before you can purchase the item. Purchase failed.
