Do I need to purchase an additional copy of eReader Pro for my my Windows XP Desktop System, etc?
We require that eReader Pro must be purchased for each platform that is used on. We did this to defray the cost of the Reader on each individual platform. For example, instead of charging $80 for an eReader Pro that runs on several platforms, we decided to charge $9.95 for each copy since most people only want to use the Reader on one platform.
