Not working – Marlee Signs Review

I had bought a few of the packages but had to delete the app on my old phone to open some space when I went to download it again it said to “restore” packages and I did but now the screen on them is black and won’t work. How can I fix this I want to learn ASL and I really love this app but I can’t use it :/
