Two issues, first you do not seem to have a USB port selected. The photo shows just a pin number
Second, you need to download a copy of the OS for the phone. I would also download the latest version of the DM. Once you configure the DM you should be able to reload the fresh OS to the BB then try to do a backup restore. Donxxx8217;t rush the reloads it takes time and sometimes looks like itxxx8217;s stalled but is not.
Also it does not make a difference if you use a PC or laptop.
Good Luck and Welcome to the Forums.
