Game keeps freezing ,help anyone?

As mentioned I am actually on level 5105, but when I click into that level it shows the top picture saying level 999 and nothing else loads. Bottom pic is how main page looks, all the levels have stars. I can play the previous level once, then if I try again it freezes on the way the game ended.

Thank you for your help PrettyBubbles, game returned this afternoon & all now seems good. Appreciate your time.
