Doesnt load

Since the App Support screen goes to a screen that says forbidden to use, I will lodge my complaint here. Im using iOS 8, iPhone 6+. When I open the application, it immediately goes back to the desktop icon before it even shows the keyboard. Except for that flaw now, I love the application. It has been very useful in the past. Right now it doesnt do any good.
