New user, can't play, crashes when starting tutorial

So... Just bought in, got access to the beta, and haven't actually been able to play yet.
Game loads fine, prompts me to create a profile, gives me the opening spiel, then asks me to click on the tutorial dungeon to get started.
That's when this happens:

Every time. Haven't even been able to start the tutorial yet. Updated to the latest Unity player, tried FF, IE, and Chrome, no joy.
Please tell me I haven't wasted twenty bucks...?
