I have been trying for more then a year to list an item that I have made. I have followed procedures step by step and it says that it goes through, but when I check my marketplace listings it does not show, even when I refresh the page or relog.

I have previously had a store and sold items before when there were merchant boxes. When the change happened it seemed my store closed down and my items disappeared. I followed instructions and even deleted my magic box, however it still will not let me add my items back or create a new store. Please help?
