I've recently installed the shield pro firewall and antivirus and ever since strange things have been happening to my computer. I can't access windows update, use MSN explorer or MSN messenger. The firewall does not allow for adding exceptions manually it only prompts the user wether to allow applications to connect or not. I was using MSN explorer to check my emails and the service stopped since i installed this program, I removed MSN explorer and tried to reinstall it but it says the following file is missing and it can not be installed 'cinfo.xml' does anyone know where I can recover this file? it's supposed to be in 'c:\windows\ServicePackFiles\i386' I bleive it's part of the XP SP2 package. I get a prompt to insert the SP2 cd, but I got the SP2 by downloading it from the windows update site, and accessing the SP2 from windows update is now impossible since the firewall has blocked the site. If anyone has had problems with this firwall or knows how to resolve any of these issues your help would be greatly appreciated.
