We are having problems with Synchronizing between Windows 7 and Windows XP, SP3. The error, though not accurately captured, is "Sync maximum time difference is more than 60 secs" We tried changing this time under Preferences > Advanced and altered the Sync_Max_Time_Diff by reducing and adding the time difference but didn't work. We are running BT Sync Ver.1.1.48 synchronizing between 2 Windows 7 PC's works fine.
