Hi,
I'm using a free account and I'd like to upgrade to a custom account so I've tried to add my payment info (PAN, Expiration date, CVC) but after submit the CVC box is shown in red and payment is not performed.
Could you please help me to know what would be the problem?
Card is ok, I've paid in other sites without problems.
I've noticed that you for a 4digit CVC but in my card there are only three digits.
thanks.
