Corrupt File

I've looked in many forums but everything I see requires the file to be opened up. The error message is "File"The Ballad of Griffin" is corrupted. Opening this file may cause Musescore to malfunction." When I select open anyway it does not open it and just goes to a blank screen. There is no 'show details' option. I've tried using WinZip and that did not work either. The file is attached. I use Musescore four.
