Nevermind, turns out one of the files I was using still had some XML
stuff in it.
So now I have it working with SecurePoint OpenVPN in Windows 7:
http://sourceforge.net/projects/securepoint/
And CentOS 5.5 using openvpn 2.2.2, as well as on as Raspberry Pi,
raspbian, openvpn 2.2.1
Roland, are you attempting to connect using the GUI in Ubuntu 15.04 or
using the command line?
