Popestar, are you trying to update from client version 0.3.012? And is your updater version below 1.1.0.0? If so, I would really recommend that you just download the latest 0.3.013 to save yourself some trouble. However if you already have the latest version, try to run the updater in recover mode (from your start menu, navigate to your PlaneShift directory).
Jonah, if you\'re getting an access violation (I couldn\'t find previous mention of 0000EEEFF anywhere,
Crashes and Diagnostic Files thread included) and can\'t find any mention of it as well, follow instructions on the thread I linked to, to email Ary your dump file.
