Can't access the store... – Criss-Cross Word-Fit Review

I have completed all of the puzzles that came with the app. I have tried to access the store to purchase more, but the whole app freezes every time. On Dilemma Apps support page, the only method to contact them for help is twitter. I don't tweet! Hope they will read this and fix the problem.
