It was working OK but now it doesn't change my IP address and I found this in syslog too:
Unsupported device type 65534 for "tun0"

I re-installed openvpn -didn't help, & the .ovpn worked fine from console on a Ubuntu live USB stick so its a problem with my system.

After I launch openvpn:

Here is the output after I enter username and password:
