Can't find QuickTime Player Application
I have a Skype video call every week with a coach. All of a sudden she can no longer hear me. I can hear her fine and have tested with other people - and they can hear me fine. I am trying to troubleshoot myself, but can't really find the application. I see it listed in iCloud Applications, but the screen is blank and I can't do anything with it. Can someone please help me?
