Hi,
Just updated to the latest version and found an annoying bug (present in earlier versions of NIS too).
Runtime error 6025 popup appears after opening outlook express (pure virtual function call) and NIS icon disappears from systray.
This happens everytime I open OE. I followed the instructions and rebooted several times. This problem never occurred with NIS 2012.
The problem is caused by the antispam plugin when outlook express contains multiple accounts. I have my regular account and a gmail account set up in OE. After disabling the plugin OE and NIS2013 function normally.
