Missing Ports after upgrading to OS 10.9.5

Cubase 8.0
Macbook Pro 2.7 Ghz i7
16 GB ram
Vienna Server Pro 5

Just upgraded from 10.8.5 to 10.9.5 and now when I open a previous session I get a long list of unmapped ports to my Vienna Pro Server rack instruments. These no longer appear under VST instruments rack window, but the VST tracks are still visible in the tracks list. Anyone else encounter this?

FYI this was solved by updating VEP server
