Garageband and iMovie stopped downloading.
I recently tried to update Garageband and iMovie from the Mac App Store. However, during the download, I had to leave the building I was receiving Wi-Fi from and now the download doesn't work. My Launchpad says the apps are downloading, but they haven't made progress since. iMovie and Garageband still work, but I cannot delete them from my computer and reinstall them to remove the downloading issue. And now, I can't get the Mac App Store to work. Any suggestions?
