Westeroscraft Not Responding

Since downloading the new launcher I have not been able to open westeroscraft. I can open the launcher but when I try and play the game it opens and freezes on the westeroscraft logo. I have an Apple MacBook Air. I have checked that I have the right version of java as well as checking the connection. I have spent many hours trying to solve this problem and I still haven't gotten to the bottom of it thus any help would be very much appreciated.


Lean forward and grab!
How much RAM do you have? The game freezing on launch is a clear indicator that your computer is running out of memory.
