Lost all data after recommended update

I did a recommended update to this app, and had been expecting all the data that I had to still be there. When I went to go use the app, I discovered all my data was lost. I am not impressed with that because it was recommended in the app to update. I would not recommend updating if you dont want to lose all your data and files you have saved!
