Heya
I'm having a similar issue with that cursed chest.
1: I have redeemed all of the fable2.com rewards, as far as I know, I received a "success" message after each play through.
2: I am always signed into Live
3: The chest has never been opened
Yet the chest will still not open, and only gives me that stupid message "Go to www.fable....etc"
I had signed out, then in again, redone the chamber part up to the chest, and it still would not open. : /
I assume there is some animation of opening the chest, and since I did not see that, there is no point in checking the shops for the bonus content...
