Can't connect to PPTP from Windows7

Hi all. Having an issue connecting through PPTP on my Linode. I followed this StackScript https://www.linode.com/stackscripts/view/8517 to get me most of the way along, but cannot connect from the native Windows 7 PPTP VPN connection tool. Tailing the /var/log/pptp.log file, I am seeing the following repeated over and over:

Connect: ppp0 <--> /dev/pts/2

...</callback></callback></accomp></pcomp></magic></mru></accomp></pcomp></magic></auth></asyncmap></callback></callback></accomp></pcomp></magic></mru></accomp></pcomp></magic></auth></asyncmap> 

Here is my /etc/pptpd.conf file:

option /etc/ppp/pptpd-options
logwtmp
localip 192.168.0.1
remoteip 192.168.0.2-123

Here is my pptpd-options file:

name pptpd

require-mschap-v2
require-mppe-128
ms-dns 8.8.8.8
ms-dns 8.8.4.4

Help appreciated!
