NAV 2012 and ZoneAlarm Pro

Just upgraded my NAV to 2012 Version 19.1  and my Zone Alarm Pro will not open. It seems as if it is running in TaskManager, but I can't open the program up to check settings or review logs. It is also not appearing in my Systray.  Is this a known incompatility between the two programs? How to fix? PS I do NOT want to uninstall either program. Thank you.
