A binary is an application that you run, i.e. psclient(.app), updater(.app), and pssetup(.app). You aren\'t having an unofficial updater problem. What is happening is that you are downloading new game files and trying to use them with old binaries. The old binaries don\'t understand the new game files.
When dfryer and I finish compiling and packaging Planeshift, it will be put in the updater repository and can be downloaded from there with either updater.
