I am trying to connect through a server in the US so that I can access a game. The game is only available to US IPs. Apparently the server "is not set up to establish a connection through PPTP to this computer". I can connect through the remote desktop fine, but I want to just go through the connection at the server. I have tried several applications without luck.
I am trying the "Connect through VPN" in the windows vista connection manager screen.

I have read guides on doing it, and the configuration looks exactly like it should be, according to those.

Is this something that you have to ask for specifically or should it be possible to set this up yourself? Some programs that forward(?) the connection automatically would be very appreciated too.
