Btw, What Payment method are you using?
If you are using a "Card" method, Try using paypal insteed.
Don't have an paypal account?
Make an Paypal account at :
http://www.paypal.comAnd then link your creditcard to paypal, and it will be like using your normal card but true paypal.
Thats how i pay for almost everything. And it havn't been a problem since i did like that.
