To add to what Tony said, You are paying for the finished version not the beta. Auran is letting you beta test because you have pre-ordered. The plan is that by the time that the beta expires the finished product will be ready to be downloaded or shipped to you. You will not be charged again. If for some reason the current beta expires before the finished product is released, more than likely another beta will be available and we have been told that the beta serial number does not expire and can be used to activate the new beta.
Auran has been very good about meeting deadlines with this project. I think you will have the finished product available for download by the end of the month.
