What happened to old scores????? – The Treasures of Montezuma HD Review

This app has been one of my favorite games - right up there w/Angry Birds. But it no longer saves the scores. It starts up from the beginning every time now. It used to be in the background & I could continue. Also, old scores are gone. Please fix! I have seen lots of negative & frustrating comments. We paid for it and it worked. Now it doesn't. Not like it should. Is this by Alawar or BigFish?
