I'm a current Quick Classic user. I am attempting to get my daughter to use the software. I got her to sign up today, however when we attempted to pay for a subscription the payment page would not accept her postal code. Of course I did a number of Google searches and it seems that I'm not the only one with this error. In fact by the dates on some of the inquires it seems that the problem has been around for several years. I tried to call the support line, but they are open on week days only. Does anyone have a solution to this problem?
