Sometimes it is showing error code 0, sometimes error code 1. All with the same result.
I have reloaded ID from the disc and there is no change.
This might be too late for you, but in case someone else come looking...
I have found that this is typically caused by permission settings. We run in to this when a folder has been imported from another user.
Correct permissions and it should save, if this is the cause.
I hope this helps someone.
