I'm running a new install of win10 pro (64) . Build 14393.576
Found to get this running with minimal changes.
Set av to exclude the c:\program files\sdenternet folder
Set av to exclude all Navyfield exe files.
(I use Trend Micro I have also tested with Mcafee/Symantec/Avast)
When selecting the Navyfield short cut do it via:
start, select navyfield folder, Right click, select run ad admin.
Works for me on this system.
