I purchased coins & I haven't received them I'm having problems with the game cutting out and giving me a blank screen right in the middle of one of the levels when I'm hitting a big win or epic win and I'm trying to make one or two in the level and it just kicks me out and gives me a blank screen I have to reload the whole thing, go all the way back and by the time I do that most of the time the game is over. I lose that level and have to go all the way back to level one. It's very aggravating.
