Is this app unable to be downloaded and installed, or is it unable to be opened and used? 
If it cannot be downloaded and installed, you may need to first verify the app's system compatibility. 
If it cannot be opened and used, I recommend removing the app and then reinstalling it to confirm. 
We apologize for any inconvenience.
