I'm just trying to register my vip10 PE and catching an error "Cannot access activation server. Please check your Internet connection. The problem may be caused by a firewall". OS is Win7 pro, native firewall is DISABLED, antivirus protection is paused... Internet connection to ALL websites via browser is OK, including visual-prolog.com. Only requests to register or check new versions of VIP are broken.
I have no ideas.

Please help me to find the fault.
