Tech problems

I liked this app, decided to buy all packages, set it up yesterday and imagine how disappointed I was when the app didnt open today! It simply doesnt start!!! I wonder if I delete it and restart will it keep my purchase? ... ((( btw some words in the app are translated incorrectly : for instance, zebra is "shimauma" (shima is a srtipe, and uma is a horse) in japanese, orange is simply orengi and not daidai (daidai is the name of the color) , rooster is "niwatori"... Anyway, its good for studying other words together with my non-Japanese wife (especially when she has me nearby to correct app mistakes), so please guys do something about tech side ) thank u !
