When I say "accidentally" I mean I just deleted it and can't get it back. What happened was I put in a DVD to watch something like I usually do and when the DVD Player App opened it became unresponsive. I refreshed, turned the computer on and off again and it was still unresponsive. So I quickly looked online for some answers and I saw someone write "I uninstalled and reinstalled the application" so I just deleted it and emptied my trash... I went on the apple website to download what I thought was the DVD player but it was just an update. Also, I think I only deleted part of the app because I just dragged the picture to trash like a dummy. I also read that I just have to reinstall it from this CD... I don't have this DVD Player CD, it was already in the computer.. maybe I missed something. So in short.. Is there a way to reinstall the DVD player or find the disc to do so?
