Unable to purchase DW with 50% Off Promo Codes

[[JGACE]boiling]

I tried to use my 50% Off Promo Codes to buy DW, but after I filled in the code and clicked APPLY, nothing changed, and Promo Codes didn't take effect when I paid.
I found that other users in the forum encountered similar problems. How to solve them?
