The game loads splash screen, fetches player data etc, but then stops at a black background screen and will not progress past this point.
I waited all night long, and still nothing.
I dont have a facebook acct, so i never registered it, but i dont want to delete and reinstall because i purchased the green/blue planeswalker and i am afraid i will lose it.
This happened with the latest update, and i have not been able to play since
