Sygate personal firewall no longer exists & there will be no updates to it. I think the last version was 5.6.
Sygate have been aquired by Symantec, so they have just made sure that another good firewall bites the dust.
Kerio Personal firewall looks difficult until you get used to it. You could try the manual, which can be found here:

I wouldn't suggest that you continue using Sygate personal firewall, as you may not be fully protected.
Sygate was one of my favourite firewalls & it was not good that Symantec bought out the company. They are nearly as bad as MS.
