I truly understand that backwards compatibility is something that should be included. Unfortunately with RaceRoom not including backwards compatibility with their new release there is nothing we can do about this. We have asked about backwards compatibility, but so far it hasn't been incorporated into the sim. Our pricing structure is designed to allow flexibility when the user purchases the software (they can go for just the software, or include an update subscription, or purchase updates as desired.) It is also designed to allow for us to pay the developers for their time to create the updates. Without that the software would not be able to be developed and improved.
