"screw-up" happened some time ago, so I cannot tell EXACTLY what I did. The initial state was:
functional openvpn which does not start automatically after boot.
So I, if I remember it correctly, scan through all directories responsible for starting services during startup and found there appropriate links, so I just renamed them to be ran later. Nothing happened. Next I surprised found some app (can't remember which one) responsible for managing these links. So I used it. Since this time openvpn stops working at all. Then I applied windows solution:
sudo apt-get purge openvpn
and then install it again, but openvpn still not starting, even if i try to run it manually (which would actually suffice me for now):
sudo /etc/init.d/openvpn start
then message "open vpn started ... ok" is displayed, but ps -e | grep -i vpn shows nothing and vpn connection can't be established (and I'm very convinced I've got connection configuration correct)
so, what can be possibly wrong?

edit: I've removed openvpn again. current state is: no openvpn installed, no links in /etc/rcXX
