Hi, I bought HAL 3.0 through the mail from a Popular Science ad about year 2000. Or there abouts anyway. Since a new version comes out every year or so, do I have to buy HAL again to have the newer versions? If so, then, is there a discount price or is it full price? My 3.0 HAL was mailed from 3175 West 42nd Str. Erie PA 16506. I have no receipt, just the box the CD case was packed in.
Thank you for your help.
