I also seem to have a problem with the shop. I preordered Fallen Enchantress, I got an order number and I was informed that I will be sent an email containing the receipt along with the said order number, and that the order itself will be processed later. I understand than processing an order takes some time, but I haven't received any email whatsoever concerning my purchase, and the "Order History" page shows nothing.
I don't have the order number anymore (I though I would get it by email so I didn't save it) and I would purchase again, but I don't want to be billed twice in case the first purchase was valid.
Can anyone please check if there are any pending valid orders tied to my account?
