Crashes after purchasing all units – Chessimo 2.0 Review

The first version of this app was great, so I wanted to try out the new version. The demo worked nicely and so I decided to buy the full package for $14.99. Unfortunately as soon as I did so, I could no longer access any of the tactics problems: the screen freezes as soon as I try to open any of them. Will request a refund.
