So disappointed

So I had giving this app a 5 star but I must take back to 2 stars due to the constant freezing and booting me off the app every time I open it I have well over 200 clients information and since Monday it has not let me open the app! So angry..... I have backed up but for some reason I cant open the file! So till they fix this issue that seems to be the problem all the time I will take it back to 5 stars!
