Well, the newest version of Ubuntu is 9.X, so you need to upgrade to the latest version, not something that's still old.
And how to stop that service, depends on how it's installed/run. Some will put an entry into /etc/rc.local, some will have an /etc/rc.d/rc5.d (or rc3.d, etc.), entry to start it there, some will install in different places. Since it's not part of Linux, it's hard to put a finger on how it's run. Read the documentation that came with it.
And given the fact that you were in mid-upgrade when the system died, chances are, you'll have a LOT more problems than this one service. Best thing to do would be to backup your data (if you haven't already), and do a fresh install of the latest Ubuntu, then restore.
