FCPX crashing when I try to share a project

Question

When I try to export a project creating a new master file FCPX crashes. I can share to vimeo or youtube, or share a still image, but if I choose to share new master file then the program shuts down, and now it doesn´t even show me the report. I am using FCPX 10.1.3, but had the same problem with previous versions. Anyone has an idea about what can be causing this problem? Thanks!

Answer 1

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.
