I have same problem:
I can play in guest mode, but once I login, the links doesn't work anymore. Besides, I'm not able to login with Facebook anymore, but I can login with google.
Browser: booth Chrome and IE, and I tried Playing via Facebook
I can see the shipslog, and rejoin the last game.
Once I delete cookies, I'm loged out, and I can choose every link and it works.
Thank you very much in advance.
