Looks like Comodo is getting too complex for me to handle.
Earlier I manually upgraded to the newest version of CIS (firewall only). Before doing so I exported my old settings. The installer uninstalled the previous version, made me reboot, I installed the new version, rebooted, then imported my old settings. But all my rules are gone. So what does ‘import settings’ do? Please tell me how to get my old network security policies back. I’m not going to lose all my settings every time I need to update (and the automatic update is too problematic from experience).
