I\'m having exactly the same problem on OSX. I\'ve got the client running successfully (having first installed it yesterday when the server was down), ran all the updates and managed to connect successfully for a few minutes earlier today (about 7 hours ago).

I was halfway through creating a character when I got the \"server was shutdown by a GM\" message. Tried again after half an hour and it now tells me I have the wrong version.

My updater.app on the Mac is 1.0.2.3, and whenever I run it I get

  Server has another updater, going to fetch it...
  Checking for updates... all files are up to date!

and nothing appears to have been downloaded. Frankly, I\'m stumped.
