I'm selling downloadable products in my store, and I plan to offer a free product as a promotion every now and then. When a customer "buys" a free product only, their cart total is obviously $0.00. When I have the freecharger payment module installed and active, the customer sees the phrase "The Zen Cart FREE CHARGE CARD" listed as the payment method. Some customers are confused and think they are signing up for a new card. If I remove the The Zen Cart FREE CHARGE CARD module, the customer sees a message that states "Sorry, we are not accepting payments from your region at this time. Please contact us for alternate arrangements."

If they click on the button to continue to the next page, there are no issues, but some customers are confused by these two phrases and don't attempt to continue.

I've searched and searched the code, but I can't find where either of those phrases are generated from, so that I can change one of them to clarify that a payment is not necessary. If anyone could just direct me to the correct location in the code (for version 1.3.9h) to change either of those phrases, or if anyone can think of any alternatives that would prevent confusion for my customers, it would be much appreciated. Thank you!
