VPN service fails after update applied in Debian Squeeze

Hello everybody,

I used to log in to my office via PPTP VPN, but on last October 5th I updated my installed Debian Squeeze and it caused my VPN service (client-side) to fail. After this upgrade I'm unable to log in to the VPN server. Here follows the log:

Code:
#tail -f /var/log/messages
Plugin /usr/lib/pppd/2.4.5/nm-pptp-pppd-plugin.so loaded.
pppd 2.4.5 started by root, uid 0
Using interface ppp0
Connect: ppp0 <--> /dev/pts/2
LCP: timeout sending Config-Requests
Connection terminated.
Modem hangup.
Exit.

According to the log I saved I see the following packages were upgraded:
Code:
libnm-glib-vpn1
network-manager

as well as some others (including the Linux kernel).

I reset my VPN configuration via Gnome's Network Manager without satisfactory results.

The authentication method I use is CHAPv2.

Could you please give me a hand to solve my VPN connection issue?

Here you are some new fresh information that might be useful to debug this issue:

Oct 8 08:21:42 thunderbox modem-manager: (net/ppp0): could not get port's parent device


I think it is specially important this part: modem-manager: (net/ppp0): could not get port's parent device. This looks strange for me. However, I'd noticed this message appears when I open Virtual Box, look at this:

Oct 8 08:48:38 thunderbox modem-manager: (net/vboxnet0): could not get port's parent device

I don't want to deviate what I am looking to be solved, but I think the output above might be useful, too.

How to regain access to my VPN? Please suggest.

Various operations that it can do are described below. You can also optionally choose not to use it via reconfiguring the racoon package using dpkg-reconfigure(8). OPTIONS
A summary of options are included below. -h Show summary of options. COMMANDS
