I just added the freebie "Signs of the Sojourner: Prologue" to my shopping cart. However, can't complete checkout - the "Pay for your order now" button is grayed out (actually 'greened out').
After repeated attempts to make this work, my "Orders History" page now shows FIVE 'pending' orders for the same game. Each has a "Complete this order" button, which returns me to the unfunctional checkout page.
EDIT: logging out and back in did NOT solve the issue. Checkout still frozen.
I had the same.
I left the checkout page
I reloaded the checkout page
I then checked the gift order checkbox
I then unchecked the gift order checkbox
And then, for whatever reason, the purchase for free button was active.
