Ident safe works on 5 of 6 computers

I'm not really happy about posting my passwords in the cloud.  I'm old school and prefer to keep private encrypted files synchronized locally on my computers manually.  I wish we had the old Identity safe that was local only.

 

Regardless, I'm not a total luddite and have moved up to the latest version of Norton Internet Security on all my in lab machines and my laptop.  I have also installed and registered the new identity Safe on all the machines which include two XP Home, one Vista Home, one Win7 Pro, one Win-8 Pro, and my laptop a Win-7 Home.

 

I can login to the Norton Management System webpage and select my "Devices" page and see all my computers represented there except my laptop.  :-(  Why?  Is it because it's wireless?  I tried turning off all firewalls including the one on the wireless router but that didn't help.  I've uninstalled completely and reinstalled, still no help.  I keep my machines all updated with all current patches for all active software.  Please suggest something I've obviously overlooked.

 

Help!!!
