SYMPTOMS

CAUSE
This problem can be caused if the Crypt32.dll file incorrectly determines that the server certificate is invalid. Additionally, this problem might also be caused if you have one of the following firewall programs installed on your computer:
 * Freedom Firewall
 * Zone Alarm by Zonelabs
 * McAffee VirusScan and Firewall
 * Norton Personal Firewall by Symantec
 * BlackICE PC Protection
