i am trying to purchase a new lifetime key for anydvd and when i click on order i'm getting a message that says "shop.redfox.bz says Your e-mail address appears to be unreachable. Are you sure you want to continue?" i have had my current email address for over 20 years and its a valid email address. i also tried my gmail address and my icloud address and i received the same message with them as well. What should I do?
