I updated my ZAFF to 92.076.000.en on my XP home w/ Symantec av. I completely uninstalled the version I was using before I installed the newest one. I have not be able to access the control panel. The taskbar icon appears & disappears when hovered over by the mouse. Sometimes its up long enough to give the UI is initializing blurb. When I try to manually open ZA I receive the following message:
Validation failed: Program Files\Zone Labs\Zone Alarm\zclient.exe
C:|Program Files|Zone Labs\Zone Alarm|zhtml.dll - probably missing necessary root certificate.

I uninstalled again and reinstalled. Same message & no taskbar icon.

I discovered that in the zhtml.dll file, the certification time stamp is dated 4/7/2009 to 4/28/2010.

My question is how do I deal with this error message? Can I revert back to an earlier version that functions? I have really trusted ZA for yrs and dont want to have to find a different firewall. Any help will be greatly appreciated. Thanks!
