Client won't start; error

[GeneralCroix]

Alright, every time I've tried to start the client via the autohaven.jnlp as received from the 'Play Now' link, the splash starts, and starting out it was either so sluggish that it dragged my computer nearly into a freeze, tried to download an update that would not go at all, or, more recently, the splash starts and then nothing happens- the process just freezes.

This is the error report I got last time I tried

I'm getting this too, but no error. Just a spalsh screen, then nothing.
Last night I actually got into teh game, but like OP said, it was so slow as to be unplayable.

  I get this error too, or one very similar to it. Although mine happens randomly while I'm playing, a pop-up coming up and announcing that the game has to close and whether I like it or not outside of reading the gibberish there's nothing I can do about it.
  Others I play with in my village seem to get the same problem too.
