G'Day Kay: It is very frustrating the same thing happen to me when I started, first I had to persuade my husband to let me do it, then let me use our credit card, then I going go. Now it just takes it and I'm in there. I didn't use a different card or anything, it just went. If you continue to have problems, try a different time and also try getting assistance from the site, I know there is a contact there. Good Luck and Cheers Jani
