When adding a new device (using my license key), two things happen often: 1. suddenly folders on existing devices are empty, and only the folders will sync 2. sometimes new folders are created with the same name as the old folders, e.g. Documents(1), Documents(2), Pictures(1), Pictures(2) etc. So some files are deleted, and other files/folders are multiplied. What am I doing wrong? Now I make backups of all my documents all the time, because I cannot rely 100% on Bittorrent Sync. Windows8.1, SyncPro personal.
