Either the method you used to "recover" them corrupted them beyond repair or
the method you used to back them up in the first place corrupted them beyond
repair. However, you describe neither method, so there's no way to tell
where the problem lies. Usually when you see the message you're seeing, the
PSTs are toast, unless one of the commercial PST repair services can help.
