Credit card payment of fee to efile personal state return

I have cd/download desktop Home and Business.  I need to pay the $20 to efile the state return but I just receive a box saying CONTINUE and nothing happens.  I am not able to enter any credit card information to continue.  I can get the program to allow me to deduct the fee from my refund but that is not what I want to do.  I have paid with credit card for a number of years.  Why isn't this option working this year?
