Hi, if you cannot open your Final Cut Pro X (FCPX) library (.fcpbundle), probably it is because there is/are corrupt file(s).
To solve it, you have to:
1. Identify the corrupt file. You can create a new library to check every event file, or simply drag all event files to the bin (including "current version" file), and check them one by one with the original library;
2. Fix the corrupt file by dragging the file to the new library, and copy the backup "current version" file in the corrupt event file, if it did not work drag the file from an earlier backup file.
