Problem With Bradford's Crossword Solver In Ipad

[ringer]

Does anyone use Bradford's Crossword Solver on an iPad?: Up to very recently mine worked fine but now the keyboard fails to appear when I try to search. Any suggestions? I've tried a hard reset, and uninstalling / reinstalling from my PC. The app does not show up in the purchase history on my iPad or in the app store as it is not supported any more
