I'm happy to report your backup file works fine Graeme. It was a rather stupid bug in my companion app that was causing the backup viewer to fail. I'm going to put out an update today for both the tablet and companion app. I'm also going to be modifying the connection logic a little bit to use a multicast message either in lieu of or in addition to the broadcast message so that it's less likely to get blocked (I hope).
Thanks,
Mike
