Hi,
It might be best if you create a support ticket, then we can take this off the public forums and we can get your VPN configuration file and connect to your host server and see if we can see the problem.
When you send us the config file please also include a username and password to connect to the VPN with, and detail the problems that you're having when you're trying to connect.
Do you actually get a tunnel established? What error messages are you seeing?
