Initially everything worked, then I uninstalled the app and then I reinstalled.
The app starts but closes almost instantly. It should not be boast.
The solution is in the firewall.
The firewall of your antivirus blocks the app and brands at as unsafe (untrust).
The solution is to tell the firewall that the app is secure (trust).
I encountered this problem with the app pictures of windows 8 with the calendar and some other program.
So just tell the firewall that the app installed is safe (trust).
