Can't connect to VPN

I have disabled the firewall and tested around and still cannot connect to the VPN.
So, does Comodo block the whole VPN connection when it’s still disabled?

Because Comodo 4x worked for me when i connected to VPN, but with this version doesn’t it work at all.

And before did Comodo detect new network zones such as the VPN, the new one doesn’t at all. So i have added the ip-addresses to the trusted zones. And it still doesn’t work.

I have stopped my connection and started, to see if it was something problem there too.
But nothing has been changed. So how can i fix this problem? I really want the VPN to work.

OS: Windows XP SP3
