You extract those files out of that zip into the PlaneShift directory. It will ask you to overwrite the existing (old) ones, and you must say yes. (if it didn\'t ask, you didn\'t do it) Doing this will give you the new updater, and the files needed for it to properly update your installation. (Your updater will list itself as version 1.1.0.0 if you did this right.) Run the updater, and things should work.
