Help!! – Sudoku.com - Number Games Review

I play this game daily but today when I updated the game it would no longer allow me to open it. Any suggestions? I turned off my device and started it again. I also quit the game and reopened it, I still cannot get it to open. My only other option is to delete the game and try to reload it. This will unfortunately cause me to lose all of my progress!
