I'm sorry if this problem already posted somewhere else. I'm a newbie and don't have time to check the whole forum yet.

I'm happy to have ZoneAlarm Internet Security Suite (ZA) installed in my PC. It works well, nothing's wrong with my internet connection. The version I have with the licence is 7.0.337.000 but the licence can be used to upgrade to the latest version. Then I updated my PC with OS Windows XP Pro SP3. Now my internet connection is blocked

What can I do? I really like this software, and have no idea to change to another one...
Please help me. Thanks in advance

Operating System:Windows XP Pro
Software Version:8.0
Product Name:ZoneAlarm Internet Security Suite
