I've been using ZoneAlarm Pro 4.x for a while so when it came time to upgrade I bought ZoneAlarm Security 5.0. However, this caused some of my programs to break. Zonelabs support told me to downgrade to 4.5, but this caused some error message about "tvGetIntegrityUserName" and so I can't run it. :-( Anyone know of a solution? Suggestions for a good software firewall program are also welcome.
An update: I've since upgraded to Win2K Pro SP2 and have been using the built-in firewall successfully.
