I attempted to use the speed scrap coupon toward the purchase of a set of templates in today's SOSN. The coupon was accepted bringing my store total to zero. When I clicked on I accept the terms, this is the message I got: Error: Payment processing gateway is not available. Please try again later. Please contact administrator and report the error(s). I'm afraid that if I try again later that I will have lost the use of my coupon. Please advise what to do.
