Lost all my money – DEAD TARGET: FPS Zombie Games Review

Been playing for over a year. Got all the weapons, on level 37, and then out of nowhere, a minus sign shows up on my money. I had over 2 billion dollars!! I can't repair my armor, can't buy bullets, can't play. Loved the game, played it often. Had to delete the game as I couldn't play anymore. What's up with this????
