I am using windows 8.1. It was ok till some day before. Now when I click the windows' app button, it shows "This app can't open. Contact your system administrator about repairing or reinstalling it." So what should I do now? Any suggestion. I tried troubleshooter but it does not work and my store app is not working too (even though it does show that sign).
