Can't get it to work – Esquire's The Hardest Puzzle Ever Review

I down loaded the free version, solved the puzzle in the first level (it took me an hour), then was prompted to pay $5 to get the other levels. I paid but never could unlock the premium levels. I deleted the app and then reinstalled it, but no joy, it happened again. iTunes refunded my money, so I'm OK, but I am waiting for an update that will fix the download problems. I liked what I saw and am sure I will improve my rating of the app once I can play the premium levels.
