Currently I can log into the game just fine and can even access the shops and inventory, but when I am trying to enter an adventure, I get a never ending loading screen (dragon+shield). According to the console log, it is stuck at "initializing deck builder", immediately after verifying data and data loaded.
Is your game account name the same as your forum nick or some other? The devs need it to check your data and error logs on the game server. You can also email support@cardhunter.com with your issue, they'll handle it.
