iMovie 10 on Mavericks gives the error message above when I click on the Theater tab or try to share a movie to it? Has anyone else seen this error?
I am logged into iCloud according to the iCloud System Preference panel.
iMac, OS X Mavericks (10.9)
Set up iMovie Theater and iCloud
In order to take full advantage of the capabilities of iMovie Theater, you must be signed in to iCloud. If you are signed in to iCloud, movies and trailers shared to iMovie Theater are automatically uploaded to iCloud. You can also turn off automatic uploading, and upload just the movies and trailers you want, or delete individual movies and trailers from iCloud. For more information about the Theater, see iMovie Theater overview.
If you sign out of your iCloud account on your Mac, all iCloud movies disappear from the Theater, but they are not deleted; the movies reappear when you sign in again. If you ever run out of space in iCloud, an alert icon appears in the top-right corner of your movie, indicating that you can’t upload new movies. For more information, click the icon. After you upgrade your iCloud storage or clear space, your movies automatically appear in iCloud again.
