Is that a Windows error message? If so I would suggest you check online to see what it means.

You can also use our 'Instant VPN' template, it should work immediately after setup.

hi there

I was facing the same problem on it but not from windows 7 but it was from another thing

Do the following
x:~# nano /etc/ppp/pptpd-options

try commenting the following line:


putting # sign in start will disable the mppe and thus can help you passing gre error
