I don't know if anyone else ran into this but I've been using the Backup 14 software for quite some time successfully including Incremental Backups. Before I processed and ran the Backup 16 app I wanted to do another Incremental Backup using the v14. It found the Full Backup but said the partition had changed and couldn't use it! I rebooted and tried again and same error! Wow! Needless to say I blew it out and started fresh with the V16 version creating my own Backup Strategy. So far so good on the backup.
