Queens quest

the game is nice. i bought it with full price, $6.99, and after I started to play the bonus level, the game blocked in the dressing room. I closed the game, restart my mac, even everything goes well (other apps), but nothing happened. So, I paid a full price for half of game. I am very disapointed.
I wanted to uninstall the game and install it again, but it’s show me, if I reinstall the game I have to pay again half of the price. I am sorry I lost money for almost nothing.
