Please help me

I hope somebody can help me.
I played HK FEZ, but for a time I stopped playing. I had't got enough free time. Later I tried to return... but can't because the program doesn't want to update itself. I tried to find a newer client, but found nothing like that. But found, that the server is IP blocked? or something or; the game had shut down? or I don't know.
Some Informations please! What is with the game, server, ect., can I somehow start the program, if yes, how?
Please help me.
