iMovie Crashing and Won't Update or Reinstall
iMovie crashed every time I try to import media. I have updated to the latest operating system. I am trying to update iMovie but I get the message "To update this app, you need to accept it on the Account page in the App Store". I have tried deleting the iMovie app so now I don't have it al all. I have signed out of the app store and restarted my macbpook. When I signed back into the app store it still has the same problem. So now I have no iMovie at all. I urgently need a fix to this as I am a teacher creating online resources and schools here are about to close. Please help!
