Ok so i started playing ffxi a couple weeks ago(played 4 years earlier but quit due to me being busy and not having a lot of time playing) I started and im already a lvl 13 thf. Ok so heres the problem. I bought myself a vanilla visa gift card and i thought it would work because i previously purchased a different visa prepaid gift card (its not Vanilla Visa. It was an all access visa prepaid debit card) and thought it would work. I went to the membership info page and went to the payment info page and started to enter my vanilla visa gift card. After I verify the info, i keep on getting an error that i have an invalid card and the message says that i either entered the wrong number or the server is down. I tried this around 4-5 times and i keep on getting this message. Anyone have any solution?
