Have the word genius app on my ipad 2 and it works fine, i can go to settings and change the board size, time limit, and word length. I purchased a second ipad 2 and installed the same app but it will NOT allow me to make changes in the settings. It registers the change but when I click save it kicks me out of the app. I have uninstalled the app and reloaded it but it still wont allow changes. Any ideas why?
