Restoring a project from the backup file.

I'm wondering how to use the backup file of the project effectively.

I had a project that was corrupted after a crash on X. The timeline came back
with repeated clips and missing graphics and little relation to the timeline before the crash.

As FCPX didn't recognise the fact that the project had been altered, it didn't offer the option to restore from back up. Attempts to open the backups get the 'must be opened within FCPX' response.
I had to use textedit to alter the currentVersion.fcpproject and force FCPX
to use the back up. Easier way surely??

Using 10.8.2 & 10.0.6

Well, its not elegant but this how I retrieved it:

Close FCP X, Delete the CurrentVersion.fcppro for the corrupted project. Rename the Back up as CurrentVersion.fcppro and replace. Reopened FCP X then it worked OK.
