Collectible Card Game Headquarters

Downloaded xMage yesterday and everything was fine. Today I tried to open it and when I click launch client I get the 'Java.lang.Nullpointerexception' error. I've deleted all files and redownloaded and I'm still getting the error. Anything I can do to fix?

I'm on a Mac, btw.

I can confirm this is crashing on OSX 10.10.3 (Yosemite)

It would appear from the server logs that the server is crashing due to being unable to connect to the JDBC database. I am attached both client and server logs below.
