Legal action possible? Wondering... – Cars: Fast as Lightning Review

I have the same problem as most if not all of the 1 or 2 stars reviews. Progress lost and now game won't open. Many of us has spent money on the game to only have what was purchased taken away from us. Does that constitute as theft or fraud? Some have spent in the hundreds as I've read and that's crazy to lose all that you have bought after spending money.
