I have tried to install and reinstall BB link/blend several times on the computers, but it will not backup (tried on 3 computers (2x windows 10 and 1 Mac Os)). The BB10 software on the passport is 10.3.3.2163. On the Windows 10 machines it identifies the content of the Passport but will not back up. I will try again on an xp machine later. I can not find any help on this matter. Please assist
