I'm just going to go out on a limb here.
Did you notice that when you copied over the new binaries if it overwrote your old config? You're gonna have to give us more information. What are you trying to run? Minilogin? Public? Is it on a dedicated server?
Telling us that you got an error after you updated doesn't tell us what we need to know to help you. That's like saying I go to the doctor and telling him I'm in pain.
