SAVE BUG? Game cannot be saved

I downloaded this game and had played it for 2 hours, it’s a pretty great game with all the fancy graphics and multiple characters to pick. However, after I closed the game and turn it back on, all my saves and game progress were lost. I repeated playing for many times but the issue still happened the same. When I reported the problem to the Koch Media developer, they gave me the really unprofessional solutions and doesn’t help even a bit. Now I just wasted my $25 (+tax) and getting none of benefit from it.
