No, I'm sorry for not explaining further :} There is a separate patch.zip that you need to download and extract into your PS folder, overwriting some older files. If you've taken care of this already and then ran the updater and you were able to play the game before this access violation, everything should be okay.
If the updater is giving you trouble, then it's likely that you haven't patched completely.. Can you try again? Make sure that you don't have any PlaneShift processes running (reboot), then open patch.zip and put all of those files into your main PlaneShift folder, clicking yes to overwrite.
