Okay, so I've been having nearly all the issues here since the new server that everyone else has been having. Not being the admin, not finding the Skylab server, updater not working, etc..
Discovered a fix for that... Delete your PS client, and any files associated with it, including in -Library-Application Support-Planeshift
Then, redownload the client, and once it's finished downloading, PLACE THE PS FOLDER IN YOUR APPLICATIONS!!!! Not the whole thing, just the Planeshift folder...This should fix the admin issue, and next time you open up PSLaunch, voila! Run the updater until it finishes, boot up PSclient, and enjoy!!
Hope this helped another afflicted Mac user like myself
