Hi, I'm using a VISA Electron Card with all my internet purchases. It works everywhere except on this page. A few months ago I was able to upgrade my account with my regular card, then I changed card for a few months and when I changed back I got this message:

Payment failed. Please make sure that you have sufficient funds and that your credit card has not expired, if you're using one. To see your current payment details please go to your subscriptions page. If you still get this message after updating your payment details please log out, log in and then try again.

I did when the message said, but it still doesn't work... Please help me!
