Good morning.  I have what I hope is a quick question.  If you purchased an item and the creator updates it, what would be considered a reasonable price to pay for something you already own?  As an example, I have an earlier version of the Jousting Grounds in my files.  Today I noticed there is an update version just released that is only available for Studio.  The original was Poser.  Should I have to repurchase, or should there be a discount or free update for those who already own the product?

Thanks.
