I'm not sure if this has been posted here already. I have ZA Pro 5.0 and my subscription has expired already for some features. I am left with the firewall and program access control. Now I am planning to install Win XP sp2. I am not sure if my handicapped ZA, if that's a good description for it right now, would pose a problem with the install. Does anybody have an idea about this? 'Cuz I was planning to remove 5.0 and install the ZA firewall only.
