pasted this from a reply in another thread. Love the lite version of this game so it would be great if some fix became available soon!

Hi,
I got the exact same problem on my 2nd gen. Itouch.
When choosing a difficulty level the maps scroll up until the one i've already played is about to enter the screen, and then it freezes.
Don't have any problem with the lite version, so i'm guessing it has something to do with that online-leaderboard thing, Feint.

Need a fix quick!! The game is so great otherwise...
