Problems all the time

There are always problems with this app. I paid $9.99 for the scrabble version with no ads. But it will still shut down on me and wont work for days or weeks at a time. Just today they sent me an email that my password had been compromised and that I should reset. I did so, but it still says email and password do not match! So frustrating!!!! Its always something. What is it with the people in charge of this game??!!
