Erases progress every time I close - please fix!!! – Nonogram Plus Review

I enjoy this app so much, it is my favorite nonogram application as far as design. However, every time I close it out all of my progress is lost :( I have tried deleting and reinstalling and it did not help. The update did not help either. I hope they come out with an update that works - it would be a 5 star app if so.
