Can't connect to VPN via PPTP on Lite

[bfb]

Thank you. The mystery is that I have done all  this seeral times on other machines, going through all those steps, including saving the password, checking the pw details etc, and all that has always worked on other Linux and non-linux systems.
On this machine it works for the Windows7 partition, so it isn't a problem with the details I am entering, nor with my connection.
It also works on Xubuntu on a laptop connectiong by Wifi to the same Internet box.

It is only on this installation of Lite that it doesn't work.

I am entering the details directly into the Pop-up Network Connections in Control Centre
